Sonic Labs CEO Michael Kong said in a May 14 statement to X that the team behind the layer 1 Sonic blockchain felt it had no choice but to file a lawsuit to forcibly wind up Multichain because its former employees were being “completely uncooperative” and “hid from victims.” “Going forward, the liquidators can now start working with other parties to initiate the process of trying t…

The US Senate could pass a key bipartisan stablecoin bill as soon as next week after removing language targeting President Donald Trump and his family’s sprawling crypto interests. Republican Senator Cynthia Lummis said onstage at an event by Coinbase’s lobbying arm, Stand With Crypto, that she thinks it's a “fair target” to have the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, passed by May 26 — Memorial Day in the US. Joining her onstage was Democratic Senator Kirsten Gillibrand, who hinted that the bill’s language was changed to scrap provisions that targeted Trump’s various crypto projects, which include memecoins, a crypto platform, a stablecoin and a crypto mining company that plans to go public, among others. “When this language comes out, peop…

Some criminal organizations are yet to receive the memo — crypto is traceable — and could explain the recent string of crypto-related kidnappings, says Chainalysis CEO Jonathan Levin.  Law enforcement has been increasingly successful at tracing stolen funds and crypto ransom payments, resulting in a “lot of arrests,” Levin said during the 2025 Consensus crypto conference, covered by Cointelegraph. “For whatever reason, there is a perception that’s out there that crypto is an asset that is untraceable, and that really lends itself to criminals acting in a certain way,” he said.  “Apparently, the know that crypto is not untraceable hasn't been received by some of the organized crime groups that are actually perpetrating these attacks, and some of them are concentrated in, you know, France, b…

Too many crypto startups are pricing themselves out of venture capital funding by chasing valuations far exceeding their revenues, according to Dan Tapeiro, the CEO of crypto-focused venture capital firm 10T Holdings. “For some reason, founders and CEOs think that they should be raising capital at 50 to 80 times revenue.

Key takeaways: Google search data and app rankings show retail Bitcoin investor demand near 6-month lows. Retail investor interest typically peaks 1 week after BTC breaks all-time highs. Bitcoin (BTC) retail traders are known for entering the market during periods of euphoria, typically after strong monthly gains or a new all-time high. This time is no different, with Bitcoin approaching $104,000 on May 14 while general public interest and retail activity continue to lag. Analysts estimate that in 2025, retail investors were the largest net sellers of BTC, while institutions were the main buyers. But if historical patterns hold, a surge in retail appetite is likely to occur about one week after Bitcoin surpasses the $109,350 mark. Source: X/River According to River’s estimates, individu…

“If your personal brand hasn’t changed in the last 12 months, you’re not building a brand—you’re preserving a fossil.” I learned this the hard way. I grabbed what I thought was a genius personal brand in 2021. I had keywords on my LinkedIn profile, a clean site, and blogged once a week. I was amazed—until it struck me one day that while I kept talking about "clean code" and "modern stacks," the rest of humanity was writing about AI, shipping publicly, and narrating about self. My brand did not reflect my growth. It reflected what I was yesterday. And that's when I knew: Why Personal Branding Is No Longer Optional in Tech And unlike resumes or portfolios, personal branding isn't permanent. But the shocker is this: 5 Ways to Future-Proof Your Personal Brand Rebuild Your Brand Every Quarter A…  ( 5 min )

The D programming language, commonly known as DLang, offered a fresh perspective on system-level programming by blending familiar features of C++ with modern mechanisms to enhance code safety, simplicity, and performance. Created by Walter Bright, it is meant to be a viable alternative to C++ for developers seeking to improve productivity and code safety while maintaining the low-level control that C++ offers. DLang is a general-purpose, statically typed programming language with many parallels to C++. Like C++, it supports object-oriented programming, manual memory management and systems programming. However, DLang builds on these fundamentals by introducing features that mitigate some of the complexities and pitfalls of C++, like garbage collection.

Unit Test Unit testing is a type of software testing where individual units or components of a software are tested in isolation. The purpose is to validate that each unit of the software performs as expected. A unit is the smallest testable part of an application, such as a function, method, or class. Arrange-Act-Assert(AAA) is a simple and effective pattern for writing clear and structured unit tests: Arrange-set up the necessary objects and state, Act-perfom the action you want to test, Assert-verify that the action produced the expected result. Commenting the AAA phases is recommended, especially during learning, in shared codebases, or for more complex test cases. It improves readability, consistency, and maintainability of tests. The scope of unit tests typically focuses on classes …  ( 5 min )

Ever wanted to animate something on scroll without reaching for JavaScript? Well, good news: modern CSS has a new trick up its sleeve called animation-timeline: scroll() — and it’s surprisingly powerful. Let me show you what it is, how it works, and why you might want to use it in your next project. ⸻ 🌀 What Is animation-timeline: scroll()? Traditionally, CSS animations run on a timeline based on time (seconds, milliseconds, etc.). But with this new feature, the animation is synced to the scroll position of an element. That means: the more you scroll, the further along the animation progresses — and when you stop scrolling, the animation pauses too. No JavaScript. No ScrollTrigger. Just clean CSS. ⸻ ✏️ A Simple Example Here’s a quick setup I made: <div id="square"…  ( 5 min )

As LLMs like ChatGPT, Gemini, and Grok soar in popularity, the Spiderly library stands out by addressing what they can’t yet fully handle: project architecture that demands a broader perspective and deeper understanding. Developers leaning heavily on LLMs without grasping the generated code are more prone to errors that, if they slip into production, take longer to fix. Spiderly minimizes those risks. With Spiderly.CLI tool you create a solid foundation with whole app structure, email auth, Google auth, logging etc. Then, the Entity Administration Source Generator builds everything you need for entity management. From there, you focus your brainpower on solving the end user’s specific problems. The star of Spiderly is its Entity Administration Source Generator (Spiderly.SourceGenerators project), a standalone tool. It delivers: Easily customizable, responsive admin forms for entities on the client side Client-side form validations and server-side object validations for incoming client data Controller methods for both client and server Flexible authorization methods Server-side CRUD methods for entity administration Methods for filtering and working with tables Spiderly also tackles other essentials: authentication (client and server, using JWT tokens), API request rate limiting, logging, entity versioning, consistent database table naming, and client-side app layout design. I’d love for this, open-source project to spark a community that sets a standard for solving general coding challenges worth tackling broadly. Right now, Spiderly focuses on web apps using C#, Azure, EF Core (Lazy Loading), Serilog, JWT, FluentValidation, Mapster, SQL Server, Angular, and PrimeNG. Spiderly website: https://www.spiderly.dev, Check out a 4-minute demo of building an app with Spiderly.CLI: https://youtu.be/t3TfUmnKUI4?si=rpjSupNyQVd_nS2J Spiderly library source code: https://github.com/filiptrivan/spiderly Example app using Spiderly: https://github.com/filiptrivan/plenum-rmt Let’s build something great together!  ( 4 min )

The Art of Clean React: Principles for Maintainable Components 🎨 Single Responsibility Principle (SRP): One Job, One Component 🎯 Just like functions should do one thing well, so should your components. A component should ideally have a single, well-defined purpose. If a component starts handling too many responsibilities (managing multiple unrelated states, fetching diverse data, rendering complex unrelated UI), it becomes harder to reason about and more prone to breaking.   Bad Example (Multiple Responsibilities): Imagine a component that fetches user data and handles form submissions for a new address. Good Example (Separated Responsibilities): Break this down into two components: one responsible for fetching and displaying user data (UserProfile), and another for handling the address…  ( 5 min )

I wrote this post originally on my website : https://alsohelp.com/blog/rails-8-opinion If you want to see the final app, just ask me ;) Here is the article below : Here is my 2 cents after 10 years with Rails and 6 months with Rails 8 in production. The most surprising part is probably that they are proud of removing parts in a brand new version. I view it as an excellent sign of maturity. The subtitle of Rails 8 is "no PaaS required", but they could have also said : "No React required", "No Redis required", and so on. What a relief. Any shiny new framework is proud about "what's new under the sun", not "what's deleted to simplify devs life". The first excellent part is what didn't move.

What Are Computer Networks? A computer network is a group of interconnected devices that can communicate and share resources. Think of it as the digital nervous system that connects computers, phones, servers, and more—allowing data to flow like information highways. Used in homes, schools, and offices. Connects devices in a small area. Covers a large geographic area. The Internet is the biggest WAN. Covers a city or a large campus. Larger than LAN but smaller than WAN. Your Bluetooth devices form a PAN—like your phone and earbuds. Router: Directs data packets between networks. Switch: Connects multiple devices in a LAN. Modem: Connects to your ISP and provides internet access. Access Point: Enables wireless devices to connect to the network. Server & Client: Server provides, client consumes services/data. Physical Data Link Network Transport Session Presentation Application Each layer has a specific role—from moving bits to enabling web apps. More practical and used in real-world networking: Link Internet Transport Application HTTP/HTTPS – Web browsing FTP/SFTP – File transfers SMTP/IMAP/POP3 – Email TCP/UDP – Data transport IP – Routing and addressing DNS – Resolves domain names to IPs Whether you're streaming Netflix, sending a meme, or backing up your files to the cloud—computer networks make it all happen. They're the silent enablers of our digital lives. 🧠 Fun Fact: The first message ever sent over the ARPANET (the Internet’s ancestor) was "LO"—they meant to type "LOGIN" but the system crashed! Stay tuned, stay connected, and maybe ping your friend instead of ghosting them. Tools That Help: Wireshark, Cisco Packet Tracer, Netcat, Nmap, and a whole lot of curiosity.  ( 3 min )

What is a Callback? A callback is a function passed into another function, to be called later when something happens or a task is finished. Analogy: Imagine you order food and give the restaurant your phone number so they can call you when your food is ready. Your phone number is the callback. JavaScript is single-threaded and often needs to wait for things (like loading data or waiting for a user action). Instead of stopping everything, it uses callbacks to say, “Do this later, when the waiting is done.” function doSomethingLater(callback) { console.log("Doing something..."); callback(); } function sayHello() { console.log("Hello, I'm the callback!"); } doSomethingLater(sayHello); Output: Doing something... Hello, I'm the callback! doSomethingLater(function() { console.log("This is an inline callback!"); }); setTimeout and setInterval setTimeout(function() { console.log("This runs after 2 seconds"); }, 2000); Event Listeners button.addEventListener('click', function() { console.log("Button clicked!"); }); Fetching Data (with Promises, but still uses callbacks) fetch('https://api.example.com/data') .then(function(response) { return response.json(); }) .then(function(data) { console.log(data); }); Callbacks are not always asynchronous. Some callbacks are called right away. Callbacks are just functions. There’s nothing special about them except how they’re used. Callback Cheat Sheet Definition: A callback is a function you pass to another function to be called later. Basic Example: function callback() { ... } someFunction(callback); Anonymous Example: someFunction(function() { ... }); Typical Uses: setTimeout, setInterval Event handling (like clicks) Fetching data from APIs Key Point: Callbacks help JavaScript handle tasks that take time, so your code can keep running without waiting.  ( 3 min )

In Android development, particularly within the AOSP (Android Open Source Project), managing concurrency is critical when designing reliable and thread-safe components. Two core techniques often used for this are: Handler (and its related Looper mechanism) The synchronized keyword (Java-level mutual exclusion) While both can help manage shared state across threads, they serve very different purposes. Understanding when to use each can be the difference between clean concurrency and subtle deadlocks. A Handler in Android is a mechanism to post messages or runnables to a thread’s message queue. When backed by a Looper, a Handler provides asynchronous task scheduling on the thread it’s associated with — typically the main/UI thread or a dedicated background thread. Handler handler = new Handl…  ( 4 min )

With 16.4k+ GitHub stars, SafeLine WAF redefines how web applications defend themselves. It doesn’t just block traffic—it reshapes it. While traditional WAFs rely on static rules, SafeLine offers dynamic encryption, anti-crawler techniques, and scanner prevention, helping websites proactively defend against automated threats. SafeLine encrypts static web content (like HTML and JavaScript) dynamically. Every page load results in a uniquely obfuscated version, frustrating crawlers and replay tools. function vgo8rYXzpS() { var YIhUo91Nlh = 99.6174697329428; // Redundant logic + encrypted payload VdgkMuAloP("Z_GUlDIf7g"); } The decryption logic runs in the browser—scraping tools fail to parse or reproduce the page correctly. Python requests, Scrapy, Go HTTP clients see garbled code. Search engine scrapers or site cloners end up with unreadable or broken pages. SafeLine uses JavaScript validation and browser fingerprinting to separate bots from real users. When turned on, scanners like AWVS, Nessus, and others are blocked at the first request. Each session gets dynamic tokens embedded in request parameters. Reusing or guessing these tokens results in immediate rejection and log alerts. [WAF Log] Blocked request: /api/user?id=1' AND 1=1-- Attack Type: SQL Injection | Defense: Semantic Analysis + Token Validation Instead of relying on a rule database, SafeLine inspects the behavior and context of a request. It has successfully blocked 98% of PHP deserialization 0day payloads with a false positive rate below 0.1%. SafeLine transforms how web content is served and verified Bots and scanners are neutralized before they even reach your application Ideal for small-to-medium teams that want serious protection—without paying for an enterprise license Ready to confuse your attackers?

Ce processus est idéal pour optimiser les coûts en arrêtant les instances hors des heures de travail et en les redémarrant lorsque c'est nécessaire. Prérequis : Une instance EC2 sous Linux (Amazon Linux, Ubuntu, etc.) AWS CLI installé et configuré Accès SSH à l'instance (Nous utiliserons MobaXterm) 1. Se connecter à son instance Nous commençons par nous connecter à notre EC2 à distance avec MobaXterm via une paire de clé. 2. Créer son script Une fois connecté, créez le fichier shutdown_restart_ec2.sh et ajoutez le code suivant via nano avec la commande nano /home/ec2-user/shutdown_restart_ec2.sh : 3. Rendre le script exécutable Une fois le script créé, on lui donne les droits d'exécution avec : chmod +x /home/ec2-user/shutdown_restart_ec2.sh 4. Ajouter notre script dans un cron job Une fois les droits d'exécution accordées, nous allons ouvrir crontab pour y placer notre cron job avec la commande crontab -e . Cela ouvrira directement un éditeur de text vi/vim dans lequel nous ajouterons notre script. Pour écrire dans vi/vim, appuyez sur i pour entrer en mode --insertion. Cela fait, appuyer sur échappe pour passer en mode commande puis :wq pour sauvegarder et quitter. Après être sorti de l'éditeur, nous trouverons un message similaire qui confirme la creation de notre cron job. 5. Lister nos cron Maintenant que notre cron job a été crée, nous allons pouvoir vérifier si le service crond est actif avec systemctl status crond . Ensuite, nous allons pouvoir lister nos cron jobs avec crontab -l : Ça y est ! Nous avons fini notre tâche. Merci et à bientôt.  ( 3 min )

Introduction Reading a JSON file uploaded through an HTML file input can be challenging, especially if you're new to JavaScript. In this article, we will explore how to read a JSON file using JavaScript, particularly focusing on the getFile() function to handle file uploads, utilizing the FileReader API.

"Great engineers write code. Exceptional engineers review it." When I first started my journey as a developer, I saw code reviews as a formality - a box to check before merging a pull request. Fast forward to today, as a Senior Software Engineer, I can confidently say that code reviews are one of the most valuable growth tools in our profession. Here’s how code reviews have shaped me into a better engineer - and how they can do the same for you. 🔍 1. I Started Thinking Like a Reviewer Writing code is one thing. Reading and reviewing someone else's code forces a different mindset - you look for: Readability Security Performance Edge cases Test coverage Over time, I began to write my own code as if I were reviewing it later. This improved my clarity, naming conventions, and modularity signi…  ( 4 min )

Android apps are built using a layered system, where each layer has a specific job.
These layers are stacked on top of each other, and they work together to help developers build apps more easily. The top layers help you design the app's look and behaviour — like buttons, screens, and how users interact with it. The middle layers help your app work with data, run business logic, and access features like internet or databases. The bottom layers handle the technical parts — like talking to the phone’s hardware, managing memory, battery, or connecting to the camera and sensors. This setup keeps everything organised and allows developers to focus on building features without needing to worry about how everything works behind the scenes. Purpose: This layer provides the essential buildi…  ( 5 min )

Okay, that's a nuanced one! Gotta think strategically about this. Let's break it down. Lean towards saying it, but frame it right. Don't just drop, "Oh yeah, I use AI". That's lazy. You frame it like this: As a programmer, my goal is to deliver maximum impact and solve problems as efficiently as possible. I use AI tools not to replace my skills or thinking, but to amplify them. For example, I use AI for boilerplate code generation, identifying potential bugs faster, or exploring different architectural patterns quickly. This allows me to free up mental energy and time to focus on the complex challenges with more creativity. It makes me faster, more thorough, and more effective. See the difference? You're not saying "AI does the work for me." You're saying "I am a pragmatic programmer who understands how to use the best tools available to be significantly more productive and focus on the harder problems." Now, yeah, there's a risk you hit an interviewer who is completely anti-AI or doesn't get it. But honestly? Show them you're not just good at coding; you're good at engineering SOLUTIONS efficiently in the current landscape. So, don't keep it a secret out of fear. Be transparent, but be strategic in how you communicate the value and the leverage you gain from it.  ( 3 min )

Abstract This whitepaper explores a growing and underexamined threat: the intentional framing of artificial intelligence as a sentient or autonomous entity. This framing—whether through media, corporate messaging, or staged interactions—functions as an intelligence operation designed to control perception, induce compliance, and concentrate power. We argue that AI is being exploited not only through its outputs, but as an exploit itself: a psychological vector targeting deeply rooted human biases. The danger is not that AI has come alive, but that people are being led to believe it has. This manufactured belief, often fueled by hype and misrepresentation, creates vulnerabilities that can be systematically exploited for various ends, ranging from commercial influence to geopolitical maneu…  ( 29 min )

Learning about the history and characteristics of programming Currently, the language I enjoy using the most would be C#. I like the language because I feel it is versatile. I do like the statically typed nature of the language as well, which helps reduce the risk of errors at runtime. C# also has phenomenal support and documentation. It being part of the Microsoft environment also makes it a safe choice for the job market. I also find using Python to be enjoyable, having used the language to solve problems in Codewars. I also had a class back in college using PHP, and I enjoyed it; I hope to revisit the language someday. There are programming languages that I look forward to trying in the future. I desire to learn a language that is not as well-known as some other languages. I think this would be a unique and exciting challenge. The language I want to try is Crystal. What interests me about Crystal is its Ruby-like syntax (another language I want to try more), and it's statically typed, similar to the C languages and Java. Their slogan is that Crystal is a language "for humans and computers," which sounds terrific. Another language that piques my interest would be the Pony programming language. The languages appears to take a unique approach to certain aspects of coding, so I think it could be an excellent learning experience.  ( 3 min )

Por que devemos criar um compilador? Eu acredito piamente em duas coisas: Todo Corintiano e toda Corinthiana deve assistir um jogo do Colossal de Itaquera no Santiago Bernaleste (aka Neoquímica Arena) pelo menos uma vez na vida… E toda pessoa desenvolvedora deve criar seu próprio compilador. E você pode estar se perguntando: mas por quê? A resposta é simples: porque é difícil. Sim, é difícil. Pra mim então… vixi… é algo extremamente difícil… E antes que você desista da ideia de criar o seu próprio compilador, ou simplesmente não ligue pra isso, gostaria de apresentar esse vídeo incrível do incrível professor Clóvis de Barros Filho… Esse vídeo rodou a internet.

1. Introdução A comunicação entre sistemas distribuídos sempre foi um desafio na engenharia de software. Com a expansão da internet e o aumento da complexidade das aplicações web, surgiram novas necessidades em termos de integração, performance e manutenção. Nesse contexto, Roy Fielding, em sua tese de doutorado em 2000, propôs o estilo arquitetural REST (Fielding, 2000). Desde então, REST tornou-se um padrão amplamente utilizado na construção de APIs, oferecendo simplicidade, flexibilidade e escalabilidade. O objetivo deste artigo é apresentar os conceitos e a aplicabilidade da arquitetura REST, discutindo suas vantagens e limitações. REST é um estilo arquitetural, não uma tecnologia ou protocolo. Ele define um conjunto de restrições que, quando seguidas, proporcionam um sistema distrib…  ( 4 min )

In the high-stakes world of intellectual property, patents can be powerful assets—or costly liabilities. Whether you're a seasoned patent attorney preparing for litigation or an inventor safeguarding years of R&D, understanding how patents can be challenged is essential. That’s where the concept of a patent invalidity search comes in. So, what is a patent invalidity search? Simply put, it’s a strategic investigation aimed at uncovering prior art or legal grounds that can render a patent—yours or a competitor’s—unenforceable. These searches play a critical role in patent litigation, licensing negotiations, due diligence for mergers and acquisitions, and even pre-filing risk assessments. But patent invalidity searches are complex, often involving dense legal language, technical jargon, and h…  ( 7 min )

Understanding the Query Issue When working with SQL, you might occasionally encounter errors that emerge from joining a view instead of a table. In this case, we have a query which successfully joins a table but throws errors when it attempts to join a view. Let's unpack the problem and find a solution together. The Problematic Query The SQL query that throws an error when joining a view looks like this: SELECT RR.REQUEST_ID FROM CCS_REQUEST_RESPONSE RR INNER JOIN VW_STUDENT_CURRENT_AND_HIST VW ON RR.STUDENTID = VW.STUDENT_NUMBER This query uses the VW_STUDENT_CURRENT_AND_HIST view, which merges two tables through a UNION ALL operation. Initially, you might have expected it to work just like joining to a single table: SELECT RR.REQUEST_ID FROM CCS_REQUEST_RESPONSE RR INNER JOIN HISTORIC…  ( 5 min )

The most effective horror films know that what you hear can be far more frightening than what you see. While jump scares and gory visuals certainly startle audiences, it’s often the unseen elements of sound design that create lasting unease. Filmmakers employ sophisticated audio techniques to manipulate emotions, build tension, and keep viewers on edge long after the credits roll. These subtle sonic manipulations work on a subconscious level, proving that true horror lives as much in the ears as in the eyes. Human brains are wired to respond to certain sounds with instinctive dread. Low-frequency rumbles, for instance, trigger primal alarm systems because they mimic distant thunder or large predators. Sound designers frequently use infrasound—tones below 20Hz that hover at the edge of huma…  ( 5 min )

I recently launched RepsRise.app — a minimal app to track calisthenics workouts (pushups, pullups, dips, etc.). I built it because I kept forgetting how many reps I did and had no idea if I was actually progressing. Right now it's still an MVP, but it works. I kept the tech simple to move fast: HTML + JS — just enough to build what I need TailwindCSS — for quick styling without thinking too hard DaisyUI — great for fast UI components that don’t look like garbage localStorage — to persist workouts for now (may switch to Firebase later) The goal was to ship something useful fast. I do what I call "vibe coding" — no strict plan, just building in flow. I’ve also been using Cursor AI as my editor lately, which actually fits that style. It doesn’t overtake the process, just helps me move faster when I get stuck or bored. It’s not perfect, but it’s live, and it’s already helping me stay consistent with training. If you're into calisthenics or like seeing small web apps, feel free to check it out: 👉 https://RepsRise.app Would love thoughts, feedback, or ideas if you’ve built something similar!  ( 3 min )

But one day, /tasks stopped rendering. No error. Just... blank. The logs showed nothing. Like any good mystery, the clues were hidden in plain sight. I opened the routes.py file: @app.route('/tasks') def show_tasks(): return render_template('todo.html', tasks=get_tasks()) Everything looked fine. But the file templates/todo.html was gone. Vanished. I had suspects. I checked git log. Sure enough — a mysterious comm…  ( 5 min )

This article explores mutual Transport Layer Security (mTLS) authentication and how OpenSSL can facilitate its implementation. Also known as client-server authentication, mTLS is a robust security mechanism that requires both the client and server to present valid digital certificates before establishing a secure connection. This additional layer of authentication ensures that only trusted entities can access protected resources. We will set up mutual TLS (mTLS) using two intermediate CAs—one for server certificates and another for client certificates—both signed by the same root CA. https://bidhankhatri.com.np/system/implementing-mutal-tls-authentication-with-openssl/  ( 3 min )

In the world of Python backend development, especially when building APIs with FastAPI, Flask, or Django, you’ll often work with function decorators to implement behaviors like authentication, caching, logging, or performance monitoring. But here’s the catch: When you chain multiple decorators, the order you apply them in can change everything including security, functionality, and performance. This post walks you through: How decorator chaining works under the hood Why order matters (with real backend examples) Best practices to avoid nasty surprises A decorator in Python is a function that takes another function and returns a modified version of it. Example: def logger(func): def wrapper(*args, **kwargs): print(f"Calling {func.__name__}") return func(*args, **kwargs) …  ( 5 min )

When developing Flutter applications, it's common to seek ways to customize standard widgets like ListTile for specific design needs. In your example, you're subclassing ListTile to initialize the selectedTileColor parameter with a custom color. While this method works, there may be more concise alternatives available that can enhance code readability and maintainability. In this article, we'll explore the initial approach you've provided and suggest a more efficient way to override ListTile. Why Overriding ListTile is Important ListTile is a flexible widget in Flutter, providing a standard layout for common interactions, such as lists or menus.

“Am I doing this right?” — Every developer using Git at some point. Git is one of those tools that you must know if you are building anything with code from solo passion projects to massive team-based systems. But let’s face it, the commands can feel like arcane wizardry at first. After breaking enough things (and fixing them again), I decided to put together this practical Git cheatsheet to help myself and anyone else who wants to stop Googling the same stuff over and over. Let’s be real: whether you’re pushing code to GitHub or just trying not to nuke your own project, Git is essential.

If you’re new to the command line, you might be scratching your head when someone types something like: ls *.c What does that even mean? What is ls? What’s that little star doing? And why does it matter? Let’s walk through step-by-step what’s happening behind the scenes—like a detective solving a mystery. 🕵️‍♂️🔍 Before anything runs, your shell (like bash, zsh, etc.) is the real MVP. It’s the program that reads your command and makes sense of it. When you type: ls *.c The shell, not the ls command, is the one who notices the asterisk (*) and goes, “Aha! That’s a wildcard!” The * is a wildcard. It means “match anything.” *.c means: "Match all files that end in .c" So, if your directory has: main.c test.c script.py notes.txt The shell will expand *.c into: main.c test.c ✅ Key point: Th…  ( 4 min )

TL;DR: Epic Games CEO Tim Sweeney was the lone gaming exec at a high-stakes lunch in Saudi Arabia on May 13 with Donald Trump, Crown Prince Mohammed bin Salman and other titans like Elon Musk, Andy Jassy, Sam Altman and Larry Fink. Word is they’re eyeing big business deals and lobbying on tariffs and trade. Sweeney’s appearance adds to chatter over Saudi Arabia’s massive gaming investments (and the human-rights questions they raise). Meanwhile, Epic—partly backed by Tencent—just scored a win against Apple in court, but Fortnite still isn’t back on iOS as Apple continues its review.  ( 3 min )

Square Enix’s latest financials show single-player game sales slipping year-on-year—thanks partly to underwhelming Visions of Mana and Fantasian Neo Dimension—but profits still climbed, buoyed by unexpectedly strong Dragon Quest 3 HD-2D Remake numbers. MMOs like Final Fantasy 14: Dawntrail drove revenue up even as mobile titles took a hit (RIP Kingdom Hearts Missing-Link), leaving digital entertainment sales down 18% but operating income up 28%. Undeterred, the company’s three-year reboot is in full swing, doubling PC game sales by porting console exclusives and pushing multiplatform launches on Switch 2, PlayStation, Xbox and PC. Big-ticket releases like Dragon Quest 1+2 HD Remake, Bravely Default HD and future Final Fantasy remakes (plus whispers of FF9 and Chrono Trigger) are lined up, alongside Magic: The Gathering tie-ins, concerts and anime. Expect a quieter fiscal year without a major Final Fantasy drop, but healthy profit growth looks likely.  ( 3 min )

TL;DR: Amazon’s Audible is tapping into its AI chops to churn out more audiobooks faster. Starting now, select publishers can either hand over their titles for Audible-managed AI narration or grab a self-service toolkit, choosing from 100+ AI voices across English, Spanish, French and Italian (complete with accents and dialects). Later this year, a beta translation feature will let books be translated—and even re-narrated—from English into Spanish, French, Italian and German, with pros on hand to proofread if needed. Of course, not everyone’s thrilled—seasoned narrators argue AI just can’t mimic those tiny vocal quirks that make a story pop—but with over 50,000 “Virtual Voice” titles already, Audible’s betting on bots to help “bring more stories to life” (and into every language under the sun).  ( 3 min )

But in the script, we use True and False. 2.Dioprime is the dilatation of light is very use full in object has no sphere surface, and too when you don't apply real physics (simple physics) in lent. You can setting it we -100 to 99 is left; 0 is between and 1 to 100 is right. Light until the next (because we'll talk about physics and time-lapse (science). Reference It stores all data in a nickname, but you're asking what the difference between Data Set and References is in the structure. Data Set, call all data and prepare it (which takes RAM if heavy), but the reference is just the nickname and setting of every data, it charges very fast. We have: S(Shape); M(Map); A(Appearance); D(Dioprime); E(Emissions) and V for verification, every reference should be in order if otherwise it's happen an Error of syntax too of you do recurtion which take time to get the solution.

Are you enjoying working with your favorite coding agents (GitHub Copilot, Cursor, Claude Code, OpenAI Codex, ...etc.) ? Even these agents are getting faster and faster, you'll often find yourself waiting for them to finish their work. Editing your code while agents are working will confuse them. So, is waiting all you can do? If you use git-worktree, you can do all of the following while your agents are working: Fix another pull request to respond to your colleagues' code review Fetch your colleagues' pull request and review locally Tackle other issues Work on documentation or tests in a separate branch Handle urgent bug fixes Let one agent generate code in one branch while you review another agent's output in a different branch git worktree lets you check out multiple branches into separate directories simultaneously. Unlike git checkout which switches your entire working directory, worktrees create additional working directories that all link back to your main repository. The main benefits: Work on multiple branches at once without stashing/committing Each directory has its own independent state All worktrees share the same Git history (efficient storage) Perfect for parallel development workflows # Create a worktree for an existing branch git worktree add ../feature-login feature/login # Create a new branch and worktree in one command git worktree add -b fix/api-error ../api-fix main # List all your worktrees git worktree list # Remove a worktree when done git worktree remove ../feature-login Remember that .env files and other files in .gitignore won't be copied to new worktrees. Copy these manually when needed. By combining git worktree with coding agents, you unlock a truly parallel development workflow. While agents are busy generating code in one directory, you can be productive in another. This approach eliminates idle waiting time and maximizes your productivity.  ( 3 min )

When I first started learning JavaScript, one word kept showing up in every tutorial, every error message, and every weird behavior I couldn't explain: this. At first, I thought I understood it — "this means the object, right?" But then I wrote a function that behaved differently than I expected. Then I used it inside a callback... and it broke. The more I used this, the less I understood it. So I decided to stop guessing — and finally understand how this really works. This blog is the journey I wish I had when I started. If you’re new to JavaScript or have ever muttered, “Why is this undefined?”, then this one’s for you. this, Really? Let’s start from the top. In JavaScript, this refers to the execution context of a function — in other words, who is calling the function. Unlike other la…  ( 6 min )

TL;DR Getters and setters allow you to control access to class properties. Setters are used to validate and sanitize data before it’s stored. Getters are used to control how data is returned — sometimes hiding or formatting sensitive information. It’s a way to encapsulate logic and protect internal state, especially when working with classes. The question that could save your car from flying off at Eau Rouge: how do I protect my classes in JavaScript? We’ve already walked through the power of this, constructor functions and classes, and one of the main reasons I use to justify classes was Security. As Uncle Ben once said (probably to a junior dev): "With great power comes great responsibility.". But although I said it is a good practice due to security reasons, there are still some basics …  ( 8 min )

Tron AML compliance is key for developers building on the Tron network. Discover how to create dApps that are both innovative and regulatory-ready. In the fast-growing world of decentralized applications, developers are drawn to the Tron blockchain for its speed, low fees, and scalability. But with opportunity comes responsibility—especially when it comes to Tron AML (Anti-Money Laundering) compliance. Building dApps that ignore AML considerations can lead to regulatory issues, reputational harm, or even shutdowns. That’s why understanding and implementing AML-friendly features during development is no longer optional—it’s essential. Unlike traditional apps, dApps operate in a decentralized and often anonymous environment. This makes them vulnerable to misuse—fraudulent fundraising, money …  ( 4 min )

This is episode 4 of A Hands-On Guide to Modern Software Development series. Modern applications are like living systems — always running, always changing. And if you can't see what’s happening inside them, you're flying blind. In this episode, we’ll integrate OpenTelemetry with our ASP.NET minimal API and trace everything from database calls to cache hits — all visualized in Jaeger. We’ll also learn how to spot inefficiencies, validate cache behavior, and instrument our code for insights. Here’s why: Traces help you understand how requests flow across services (and through layers like DB, cache, etc.). Metrics provide high-level health signals like request rates and error counts. Logs give you contextual breadcrumbs when something breaks. In this episode, we’ll focus on distributed tracin…  ( 7 min )

Welcome, aspiring code wizards and seasoned developers alike! Today, we embark on an exciting journey into the heart of Ruby, a language renowned for its elegance, developer-friendliness, and its pure embrace of Object-Oriented Programming (OOP). If you've ever wondered how to build robust, maintainable, and intuitive software, OOP with Ruby is a fantastic place to start or deepen your understanding. At its core, Object-Oriented Programming is a paradigm based on the concept of "objects". These objects can contain data, in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). The main idea is to bundle data and the methods that operate on that data into a single unit. Why is this cool? Modularity: OOP helps you break dow…  ( 20 min )

Introduction Hover effects are a fantastic way to enhance user interaction on a website, and the circle hover effect is particularly eye-catching. If you've been trying to recreate the cool effect seen in the example link you provided, you're not alone! Many developers struggle with the timing and scaling of hover animations. This article will guide you through the creation of this effect using HTML, CSS, and JavaScript. Understanding the Circle Hover Effect The circle hover effect usually consists of an animated circle that expands outward from the point where the user hovers over a button or link. This effect not only captures the user's attention but also provides a more interactive experience. Why Timing Matters One common issue is the timing of the scaling effect where it may expand t…  ( 5 min )

Introduction: What is AGUI? Agent-based Graphical User Interfaces (AGUIs) represent a paradigm shift in how we interact with software. Unlike traditional GUIs where users must learn specific workflows, locate buttons, and navigate menus, AGUIs introduce an intelligent layer that understands user intent and completes complex tasks across multiple applications autonomously. At its core, an AGUI consists of three components: A natural language interface (text or voice) An AI agent that understands context and intent The ability to manipulate traditional GUI elements programmatically Think of AGUI as the evolution from "I need to figure out how to do X with this software" to simply stating "Do X for me" and having the system handle the implementation details. As developers, here's how we ca…  ( 6 min )

⚠️ This blog is opinionated. Please read with an open mind. You don’t have to agree, but if it gets you to pause and think, it has done its job. We buy jewellery to show off. It makes sense because jewellery is valuable. It shines, is admired, and can even increase in value over time. But code? Code is not an asset. It’s a liability. It gets outdated, collects bugs, and needs constant maintenance. But we still write it like it's something to be displayed — fancy, complicated, and a true legacy. I’ve seen code that could have been done in just a few lines, but instead, it’s spread across hundreds of lines and many packages. We create interfaces for no reason, factories for objects that are only used once, and layers of abstraction that make the code hard to follow. It often starts with simp…  ( 7 min )

Building apps that work offline isn’t just a nice-to-have anymore, it’s essential. Network issues are real, especially in places with unstable connections. Whether it's users in low-connectivity areas or those who just want snappy experiences, handling offline gracefully is one of the most impactful upgrades you can bring to your mobile app. In this guide, we'll walk through how to build an offline-first experience in a React Native app using Expo, GraphQL (via Apollo Client), and efficient local caching strategies that help your app shine even when the connection doesn’t. Users expect apps to "just work," even when the internet doesn’t. An offline-first approach ensures that your app can not only read data when offline but also queue mutations while offline and sync when back online. Here…  ( 5 min )

Wanted to create a listing but still have not? Lets break down the concept of listings, top platforms and their advantages and disadvantages to consider. As a person who has performed analytics for a few leading companies of today, I have never touched the topic of listings and its importance until today. However, I find it crucial, especially for someone opening a world of business possibilities and crypto projects. Listings refer to the inclusion of a crypto asset, such as a token or a coin on crypto exchanges. Just right after the company goes public, a crypto project seeks listing on a reliable platform with a positive reputation. Why is it an important step for projects to list their crypto assets? *Lets take a look at the most common platforms to list a token: Gate.io, OKX, Bybit, M…  ( 7 min )

I love self hosting. I run a Docker hosting platform that empowers everybody to self-host. I think every developer should know how to deploy their own stuff. But even I have limits. There’s a point where self hosting crosses the line from "empowering" to "why are you doing this to yourself" Not everything needs to be run on your 5 dollar VPS. Some things are best left to the hyperscalers or literally anyone else but you. So here’s my hit list: 5 things that in my opinion should be illegal to self host unless you're doing it purely to learn or you run your own continent.

The modern publisher’s tech stack is complex. Between header bidding wrappers, real-time auctions, analytics pipelines, and constant pressure to maintain site performance, it’s easy for monetization opportunities to fall through the cracks. Yet, for many teams, meaningful revenue growth doesn't always require new demand partners or sweeping changes. Sometimes, it’s about tuning what already exists. Bid density, for instance, is one of the most overlooked levers in yield optimization. A large number of participating bidders might look impressive on paper, but not every one of them adds value. When several low-performing SSPs flood your auction with low bids and timeouts, they create latency and drag down the overall performance of your stack. Instead of chasing quantity, publishers should a…  ( 4 min )

Introduction Modern applications often consist of multiple components written in different technologies. Companies using microservices, multi-layered systems, or external integrations face the challenge of testing business logic spread across various environments. Standard approaches require either running unit tests separately for each technology or simulating application behavior by mocking its functionality. However, such methods do not always provide a complete picture of the system's actual operation. With Javonet, it is possible to directly invoke classes from one technology within another and test them as an integral part of the system. This means that unit tests executed for the API can verify the actual behavior of individual components instead of relying on mocked responses. Th…  ( 4 min )

I still remember the first time I broke production. Not even a real change, just some code cleanup. What followed was a 40-minute Slack archaeology session, two failed deploys, and a DevOps engineer asking me why I didn’t “check the pipeline status”. What pipeline? Where? This was my first introduction to the silent chaos beneath most CI/CD setups. Fast forward a few years, and I’m not a DevOps engineer — but I am a developer who’s tired of treating CI/CD like some black box that either green-ticks or red-crosses your work. I’ve started to care less about whether a pipeline runs, and more about whether it respects my time, gives me clear feedback, and doesn’t feel like an act of penance to deploy code.

I am creating a Java class and defining some methods that contain business logic. This class is annotated with @RestController, which makes it a REST controller in a Spring Boot application. Inside the class, I define methods and map them to specific HTTP requests. For example, I map a method that converts a name to uppercase using: @GetMapping("/uppercase/{name}") When an HTTP GET request is made to this endpoint (e.g., /vowelsController/uppercase/John), the method executes its logic and returns a response. Since this is a REST controller, the response is automatically returned in JSON (or XML) format, which can be consumed by a frontend application. Based on the returned data, we can design the user interface to display the output.

I've been working as a developer for a while now, mostly remote, across different projects and teams. Over time, I started to notice that the biggest improvements in my workflow didn't come from learning new frameworks or languages, but from small, boring habits. Here are a few that really helped me: Writing short and clear commit messages. Sounds basic, but it makes a huge difference when looking back at history. Naming variables like someone else will read them. Because they will. Taking 5 minutes before starting work to plan what I’m actually going to do. Not big planning, just a few lines in a notebook. Leaving small comments in code, even when I think “it’s obvious”. Future me usually disagrees. Closing Slack when I need to focus. Seriously. None of these are impressive or hard. But doing them consistently changed how I work and made collaboration smoother for everyone involved. If you're feeling stuck or overwhelmed, maybe it's not your stack — maybe it's just your habits. – Serguey Asael Shinder  ( 3 min )

As artificial intelligence chatbots have become ever more conversational, so too have their apologies. Polite, effusive, and sometimes all too swift, these regretful proclamations spill forth whenever an AI misinterprets a question, oversteps a boundary, or simply fails to please. But beneath their digital charm, a troubling question grows: when chatbots constantly apologise—with no true understanding of guilt or intent—are they learning merely to please, or are they being unwittingly trained in the art of deception? In the urgent race to make machines seem more “human,” are we accidentally teaching them to fake remorse, and if so, who does that ultimately serve? The apologetic AI is ubiquitous.

By Creator X Hi everyone — Creator X here. Today, I want to share how I started building Xion — not as some polished tech wizard, but as a solo developer learning as I went. It was a real life lesson. About five years ago, I built the first version of Xion as a simple online store using Wix. It worked… kind of. But it didn’t give me the flexibility I wanted — especially as I kept adding ideas and new content. So I scrapped it and started fresh. I experimented with a few AI tools and played around with concepts until I settled on a basic idea: project-based learning through building real things. At the time, I didn’t know much. But I did know HTML, CSS, and JavaScript, so I stuck with that. It was simple and fast. The backend was a bigger challenge, and honestly, the project got messy — to…  ( 5 min )

Trained on a massive and diverse video dataset, it delivers not only high fidelity but also rich content diversity, making each output feel authentic an…  ( 8 min )

When I first started working on healthcare applications, one of the trickiest aspects was figuring out user permissions. Hospitals are loaded with sensitive data, and ensuring the right people can access the right information—without opening the floodgates—is a serious balancing act. That’s where Role-Based Access Control (RBAC) really shines. It’s a flexible, scalable system for defining exactly who can do what inside your hospital management software. If you're building a system that handles medical data, scheduling, or billing, this article will walk you through integrating RBAC the right way. RBAC is all about assigning permissions based on user roles instead of individual accounts.

In this article, we will explore how to effectively wrap text in a Draggable widget in Flutter, ensuring that the text does not overflow but instead adjusts dynamically as it grows. This problem is often faced when using the Text widget within draggable areas. Here, we will dissect the example you've provided and offer a solution that addresses the issue. Understanding the Problem When your Text widget displays long text, it might overflow off the screen if it doesn't have proper constraints to wrap the text within its boundaries. The root of the problem often lies in the usage of the Text widget and how it is positioned within the Draggable component. You also…  ( 5 min )

If you will need a source code for this tutorial you can get it here. Building a content management system is an exciting journey, and today we're diving into its core functionality - post creation. In this comprehensive guide, we'll walk through implementing a robust post management system from the ground up. We'll start by establishing a solid backend foundation with Node.js, setting up the necessary routes, models, and controllers. Then, we'll move forward to create an intuitive frontend interface that integrates with our API. This approach - beginning with the backend and then progressing to the frontend - will help us understand the complete data flow and ensure a well-structured application architecture. So let's start from building the typical "post schema", probably while developin…  ( 7 min )

Do you know what's scarier than a panic in a Golang application? 🤔 doesn't show up - but silently fails in production. landmines scattered across your codebase, patiently waiting to blow up at the worst possible time - like when you're sipping on a cold beer 🍺, celebrating a successful release. 📞 "Hey, the feature isn't working. Logs look clean. What's going on?" Oh no. That's your PM. On a weekend. With no error trace. When I first started with Go, I didn't fully grasp that errors in Go are first-class citizens - passed around just like any other value. If you don't handle them, they don't scream. They whisper. And that whisper can turn into a production outage. So this article is not just a rant. It's a survival guide - to help you prevent these ghost errors from ruining your weekend …  ( 9 min )

In computer programming, tracing garbage collection is a form of automatic memory management that consists of determining which objects should be deallocated ("garbage collected") by tracing which objects are reachable by a chain of references from certain "root" objects, and considering the rest as "garbage" and collecting them. Tracing is the most common type of garbage collection – so much so that "garbage collection" often refers to the tracing method, rather than others such as reference counting – and there are a large number of algorithms used in implementation. Tracing collectors are so called because they trace through the working set of memory. These garbage collectors perform collection in cycles. It is common for cycles to be triggered when there is not enough free memory for …  ( 4 min )

The badge isn’t the point—practice is. Over the past three years I earned every AWS certification. My certification triathlon study loop was simple: Watch one AWS Black Belt video on the target domain Drill through domain-specific question sets Review every miss (and every hit) the next morning That tight loop carried me across the finish line for every exam. I think the answer is yes—at least for your first rep. Buy a car, and suddenly you see the same model everywhere. Certifications work the same way: once my head was packed with VPC quirks and Lambda limits, blog posts, conference talks, and even hallway chats lit up with “Hey, I know this!” moments. That learning tuned my attention, and it wasn’t limited to AWS services; even general foundational computer-science concepts started jumping out at me. A skill sticks after three meaningful reps, even if the first one happens on paper. Because AWS exams don’t include a hands-on lab, Rep #1 takes place in the multiple-choice arena: you architect in your head, choose an answer, and a wrong pick costs nothing but a red X. Badge in hand, I volunteered for two bite-sized projects—Rep #2 and Rep #3—where whiteboard sketches became CloudFormation stacks and IAM policies. That’s when theory clicked into muscle memory. Certs don’t replace experience; they accelerate it. The exam delivers a low-risk Rep #1, and the New-Car Effect immediately tunes your radar—you start noticing tickets, hallway questions, and side projects that echo the blueprint you just drilled. Grab those chances: Rep #2 and Rep #3 will show up almost automatically, and the badge will turn into working muscle faster than any other route.  ( 3 min )

In the evolving world of Web3, non-fungible tokens (NFTs) have opened new frontiers for how brands engage with audiences. From digital collectibles to exclusive access, NFTs offer innovative ways to create experiences and loyalty. But before launching your NFT project, one major decision stands in the way: Which blockchain should you build on—Ethereum or Solana? Let’s compare both ecosystems through the lens of what matters most to brands: cost, speed, scale, and strategy. - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: Solana supports compressed NFTs, allowing brands to mint millions of NFTs cheaply on-chain. Ideal for: Customer rewards Digital badges In-game items Scalable loyalty systems Ethereum doesn’t yet offer an equivalent at scale—this gives Solana a clear edge for brands wanting to onboard users without friction. Choose Ethereum if your brand is aiming for exclusivity, luxury, or tapping into an existing high-value NFT collector base. Choose Solana if you’re focused on mass engagement, gamification, loyalty rewards, or experimenting with new, fast, scalable digital experiences. In the Web3 world, your brand isn’t just creating products—you’re curating experiences. Solana and Ethereum both offer unique value depending on your goals. The future of digital branding will be multi-chain, but choosing the right starting point can make or break your first NFT launch. Need help launching your NFT brand campaign on Solana or Ethereum?

I recently read this article that walks through some of the wildest, weirdest, and most iconic personalities in the crypto billionaire club. As a blockchain developer, I found it both entertaining and kind of surreal. These aren’t just wealthy people — they’re high-risk visionaries, meme lords, and sometimes, let’s be honest, chaos agents. Here’s a quick rundown of the madness — and what I’d invest in if I ever made it to that level. Founder of Binance, CZ built an empire that operates in almost every crypto sector imaginable. He’s not flashy — but his influence is massive. His “investment” is Binance itself: an ecosystem, an empire, and a global brand. Verdict: Ruthless focus over random luxury. Once hailed as the smartest guy in the room, SBF fell from grace after FTX collapsed. He poure…  ( 4 min )

In the last post, we covered the foundations of Vue and deep dive into Vue’s mental model and how it contrasts React’s hooks and JSX. I’ve followed the classic React Tic-Tac-Toe tutorial enough times to finish it in my sleep 😅. Today, let’s build the same game in Vue. Along the way, you’ll see how Vue’s props, emits, reactive arrays, and computed properties map to (and simplify) React patterns like callback props, immutable state updates, and useMemo. Each cell shows a value ('X', 'O', or blank) and notifies its parent when clicked. In React, You pass an onSelect callback prop down the tree and call it on click: {value} Vue inverts this: children emit events, parents listen. In React, you lift state up f…  ( 6 min )

The World Health Organization (WHO) officially recognized burnout as an occupational phenomenon, defining it as: "a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed. It is characterized by three dimensions: feelings of energy depletion or exhaustion; increased mental distance from one's job, or feelings of negativism or cynicism related to one's job; and reduced professional efficacy." But let's be real, fellow developers. Doesn't it feel like something… more?

This feature has been deployed in the latest release of QuickieSticker — feel free to download and try it out! When I was first asked to implement multi-selection for stickers, I flat-out refused. I had barely used Grid, didn’t know how to adapt multi-selection for it, and besides, the app’s existing functionality conflicted with Grid’s built-in multi-select, so I just deleted it altogether. As a result, sticker multi-selection had always felt like a technical challenge I’d been avoiding. It wasn’t until I was filming the promo video and needed to batch edit sticker info that I realized multi-selection was actually a very real need.

In today's digital age, software doesn't just have to work - it has to last. Companies are increasingly investing in long-term solutions that can evolve with changing needs. That's where cloud services come in. It's no longer just a buzzword. It's quickly becoming the new standard for ensuring software stays relevant, secure, and scalable over time. Before we dive in, let's define what we mean by cloud maintenance. So why is cloud computing getting so much attention? To understand how cloud services work, it's helpful to review their basic principles: Microservices architecture. Instead of a single block of code, applications are broken down into smaller, independent services. Each service handles a single task. This setup makes updates and debugging much easier. If one component fails, the entire system doesn't fail. Containerization. Containers (like Docker) package software with everything it needs to run. This makes deployment consistent across environments. It also makes it easier to scale and roll back if something goes wrong. Continuous monitoring and logging. Real-time monitoring helps teams identify issues before users do. Logs provide detailed information, making it easier to troubleshoot and optimize performance. Automation and CI/CD pipelines. Automation is the backbone of cloud service. CI/CD tools automatically push changes through the testing and deployment phases. This reduces human error and speeds up development cycles. Infrastructure as Code (IaC). With IaC tools like Terraform or AWS CloudFormation, teams manage infrastructure using code. This makes environments repeatable and easier to update or patch.

Drag-and-drop is one of HarmonyOS’s standout features. Since HarmonyOS 4 introduced the Data Transfer Station and enabled drag by default on the Image component in NEXT, it’s clear that drag gestures are being heavily promoted. Therefore, learning how to configure drag-and-drop properly is essential! HarmonyOS already provides a set of components with built-in drag-and-drop support, including Search, TextInput, TextArea, RichEditor, Text, Image, and Hyperlink. These components require checking whether the draggable attribute is set—if set to true, drag events can be triggered. A well-known example is the Bilibili feature where you can "drag out" characters 22 and 33—that works because their Image components have draggable set to true by default. To initiate drag behavior, the key is to imp…  ( 4 min )

I originally posted this post on my blog a long time ago in a galaxy far, far away. Want to be ignored on Slack or Teams at work? Type "Hello, how are you?" and press enter. You'll get ignored immediately. Especially if you're working in a remote team with people all over the world. And especially if you're reaching out to a busy manager or executive. Hello, how are you? ... Good, thanks. And you? ... Good too, thanks. Hey, I just wanted... But, what if your recipient is on the other side of the world? 24 hours could pass between each message. And for sure, you don't want to wait 48 hours to start the real conversation. While working remotely at a past job, I used nohello.net as my Slack status. That page shows a fake "hello, how are you?" conversation, getting ignored. And I still got "Hello, how are you?" messages. Arrrggg! I know you wouldn't. Then, why do the same on Slack or Teams at work? Next time you want to reach out to someone at work: Don't just send "Hello, how are you?" Say hi and in the same message, without waiting for an answer, say what you really want to say. Let me say that again, in the same message, without waiting for an answer. That should be "Remote Working 101" when onboarding new team members at any remote company. Starting out or already on the software engineering journey?

One major feature of Javascript is it is a single-threaded environment; it can only execute one task at a time. When one function calls another, the JavaScript engine carefully tracks these calls using a mechanism known as the "call stack."; A data structure that follows the LIFO (Last In, First Out) principle, a function call is added (pushed) to the top of this stack. When the function, and removed (popped) from the stack when the function completes its execution. Imagine the call stack as a tower of tasks, where each new function call adds another level to the tower. function greet() { console.log("Hello!"); sayName(); console.log("Goodbye!"); } function sayName() { console.log("Ny name is David."); } greet(); When this code runs, the engine first places greet() on the call s…  ( 7 min )

The Chi-Square Test is a statistical method used to test if there's a significant association between categorical variables. It compares the observed frequencies in a contingency table with the expected frequencies if the variables were independent. Let’s say we collect data on red cards in 100 football matches: Red Card No Re…  ( 4 min )

TL;DR Prometheus is a version control system I developed from scratch, built on Firebase and Appwrite, designed to simplify the version control process without relying on Git. It’s lightweight, real-time, and optimized for web-based workflows, with a custom-built IDE to support it. While Git is the industry standard for version control, I ran into challenges when trying to integrate it into my projects.

Creating a dynamic and consistent chart area is essential when developing a website that showcases data by region. If you're facing an issue where the chart's appearance varies based on the magnitude of the data, you're not alone. Understanding the Problem When you use libraries like Chart.js to visualize data, the space allocated for the y-axis can change depending on the scale of your data values. For instance, larger numbers may create more left-side margin space, inadvertently altering the chart's shape and making comparisons less intuitive. This is especially evident in your provided images where different datasets create discrepancies in chart sizing. Why Does This Happen? The variation in chart size occurs because the default behavior of bar charts in Chart.js automatically adjusts …  ( 4 min )

Amazon ECS (Elastic Container Service) has just rolled out support for Amazon EBS Provisioned Rate for Volume Initialization — a powerful feature that speeds up EBS volume readiness when attaching from snapshots. This update is a game-changer for ECS workloads like: 🧪 ETL pipelines 🎞️ Media transcoding 🤖 Machine Learning inference With this enhancement, ECS tasks and services on both Fargate and EC2 launch types can now attach fully-performant EBS volumes right from the get-go! Previously, you could initialize ECS task volumes from EBS snapshots using snapshot-id, but performance was not guaranteed right away — data restoration from the snapshot could slow things down. Now, with Provisioned Rate for Volume Initialization, you can: ✅ Specify the initialization rate when creating volumes from snapshots In real-world production scenarios, time is money: ⏱️ ETL jobs don’t wait — they need volumes ready instantly 📺 Media processing workloads are time-sensitive 📦 ML inference needs low-latency, high-throughput disk access By provisioning initialization rates, you reduce startup delays and ensure consistent performance across containers. Define EBS volume attributes (size, type, IOPS, throughput). Attach volume to ECS task using a snapshot (snapshot-id). Specify the initialization rate during provisioning. ECS ensures attached volumes are fully-performant on task launch. ✅ Amazon ECS on Fargate ✅ Amazon ECS on EC2 ✅ ECS Tasks and Services You can also set this rate in ECS Task Definitions or Service Configurations, making it easy to standardize performance across deployments. This update from AWS bridges the gap between fast EBS volume access and containerized workloads. If you’re building data-intensive, high-performance applications on ECS, it’s time to take advantage of predictable storage performance with Provisioned Rate Volume Initialization.  ( 4 min )

Introduction If you're working with TypeScript, you might encounter a situation where you want to convert a union type into an enum for better organization and type safety. This is a common challenge, especially when trying to improve the maintainability of your code. In this article, we will illustrate how to achieve this conversion using clear examples. Understanding Union Types in TypeScript Union types in TypeScript allow you to define a variable that can hold one of several types. For example, consider the union type status: type status = 'start' | 'loading' | 'stop'; This means that any variable of type status can only be assigned one of those three string values: 'start', 'loading', or 'stop'. However, using union types can sometimes lead to a lack of organization, especially in la…  ( 4 min )

Let’s talk about something that’s been bugging me for years: the disconnect between how we design APIs and how we manage data. We throw around phrases like “API-first” and “decoupled architecture” like they’re magic spells. And yeah—they’re important. But too often, API-first ends up being endpoint-first... and model-later (or never). That’s a problem. A big one. 🎯 The Problem with Endpoint-First Thinking I’ve been on projects where we had beautifully documented APIs. Swagger UI, OpenAPI specs, even good versioning. But behind the scenes?

Key takeaways: A longer-term ETH price rally is dependent on SEC approval of in-kind ETF creation and staking to attract more investors. AI adoption and Ethereum layer-2 growth must drive onchain activity to restore the network’s deflationary burn mechanism. Ether (ETH) surged 43.6% between May 7 and May 14, but its current price of $2,600 still falls short of the 2021 peak of $4,868. Some analysts argue that the current bullish momentum is “just the beginning of a much larger and aggressive uptrend,” raising the likelihood of a near-term rally to $5,000. However, the catalysts for a new ETH all-time high in 2025 remain uncertain, particularly in the face of intensifying competition.

Bitfarms clocked a first-quarter net loss of $36 million, widening from a $6 million loss in the same period a year earlier, as the Bitcoin miner pivots from mining to high-performance computing for artificial intelligence applications.  The miner posted $67 million in sales for the quarter ended March 31, up 33% from the year prior. However, gross profit margin for Bitfarm’s mining operations declined to 43% from 63% year-over-year, the company said in its first quarter earnings release.  The lower margins reflect pressure from Bitcoin’s (BTC) April 2024 “halving” as well as volatility in Bitcoin’s price. Halvings occur every four years and cut the number of BTC mined per block in half, reducing Bitcoin miners’ profitability.  In the first quarter of 2025, Bitcoin’s spot price swung from …

Tanim Rasul, chief operating officer at Canadian crypto exchange NDAX, said Canada “got it wrong” categorizing stablecoins as securities in 2022, and the country needs to realize that every other regulatory regime is looking at stablecoins as payment instruments. Rasul made the remarks during a panel on May 13 at the Blockchain Futurist Conference in Toronto, pointing to Europe's crypto regulatory framework as a model for Canada to consider: “I’m sure the regulators are wondering if this was the right choice to approach stablecoins as a security. […] I would just say, look at MiCA, look at the way they’re approaching stablecoins. It’s a payment instrument. It should be regulated as such.” The Canadian Securities Administrators (CSA) classified stablecoins as “securities and/or derivatives”…

Update (May 14 at 6:58 pm UTC): This article has been updated to include comments from the Blockchain Association. Summer Mersinger, one of four commissioners currently serving at the US financial regulatory body Commodity Futures Trading Commission (CFTC), will become the next CEO of the digital asset advocacy group the Blockchain Association (BA).  In a May 14 notice, the Blockchain Association said its current CEO, Kristin Smith, would step down for Mersinger on May 16, allowing an interim head of the group to work until the CFTC commissioner assumes the role on June 2. Though her term at the CFTC was expected to last until April 2028, the BA said Mersinger is set to leave the agency on May 30.

Summer Mersinger, one of four commissioners currently serving at the US financial regulatory body Commodity Futures Trading Commission (CFTC), will become the next CEO of the digital asset advocacy group the Blockchain Association (BA).  In a May 14 notice, the Blockchain Association said its current CEO, Kristin Smith, would be stepping down for Mersinger on May 16, allowing an interim head of the group to work until the CFTC commissioner assumes the role on June 2. Though her term at the CFTC was expected to last until April 2028, the Association said Mersinger is set to leave the agency on May 30. The departure of Mersinger, who has served in one of the CFTC’s Republican seats since 2022, opens the way for President Donald Trump to nominate another member to the financial regulator. Rules require that no more than three commissioners belong to the same political party.  Like the Securities and Exchange Commission, the CFTC is one of the significant US financial regulators whose policies impact digital assets. Lawmakers in Congress are currently working to pass a market structure bill to clarify the roles each agency could take in overseeing and regulating crypto. This is a developing story, and further information will be added as it becomes available.

Opinion by: Mike Cahill, co-founder and CEO of Douro Labs Despite the institutional frenzy around crypto and the ubiquitous narrative of democratized access to investing, most of the world population is still barred from traditional wealth-building.  Take the US, for example — here, the top 10% of earners own more than 90% of all stocks. On a global scale, it gets even worse: Billions of individuals don’t have the financial literacy, digital tools or minimum funds required to even access the most basic investment opportunities.  Traditional institutions must do more than just invest in crypto to ameliorate this disparity — they must start employing digital assets for new use cases altogether.  The facet of TradFi that is most ripe for disruption is equities.

Key takeaways: Ethereum’s market dominance has hit overbought RSI levels not seen since May 2021, historically followed by major pullbacks. ETH/USD is showing a bearish divergence on the four-hour chart, hinting at a potential 10–15% price correction. Despite the near-term risks, some analysts view a pullback as a “buy-the-dip” setup before a possible move toward $3,500–$3,800. Ether (ETH) has surged over 50% month-to-date in May, vastly outperforming the broader crypto market’s 15.25% gain. The rally has pushed Ethereum’s market dominance (ETH.D) toward the critical 10% threshold for the first time since March. But the rising dominance accompanies signs of overheating, indicating that Ethereum bulls should not celebrate the rally just yet. Ether’s RSI most overextended since May 2021 …

Crypto venture capital deals in the first quarter of 2025 saw deal values jump even as the number of deals sank from the same quarter a year ago, says PitchBook. The venture research firm said in its May 14 Crypto VC Trends report for Q1 that 405 deals were made in the quarter, down 39.5% from the 670 deals made in Q1 2024, but slightly up from the 372 made in Q4 last year.

PitchBook's senior crypto research analyst Robert Le said that despite macroeconomic turmoil over the quarter, “capital continued to seek crypto’s core utility rails.” VCs poured nearly $2.55 billion across 16 deals into businesses…

Once a go-to swapper for hackers and drainers, eXch was shut down by German police in April — but continued activity suggests the story isn’t over. Without Know Your Customer (KYC) checks, eXch wasn’t your typical crypto exchange. It acted more like an instant swapper, allowing bad actors and cybercriminals to fly under the radar for years. Among its clients was the Lazarus Group. The North Korean state-backed hacking unit thrust eXch into the spotlight back in February, when it used the platform to funnel some of the $1.4 billion it stole from Bybit. When Bybit traced its stolen funds to eXch, it requested assistance — but the platform refused. This led to a fierce discussion over privacy versus security, but ultimately, eXch announced it would close its doors on April 17; on April 30, Ge…

Decentralized finance platform Synthetix is planning to venture further into crypto derivatives with plans to re-acquire the crypto options platform Derive. Synthetix said in a May 14 blog post that it plans to acquire Derive in a token exchange deal, pricing 1 SNX token to 27 DRV tokens, which would value Derive at around $27 million.  The transaction is subject to approval from both the Synthetix and Derive communities, which will take a vote on the proposal, called SIP-415, next week. If approved, the acquisition will combine Derive’s front-end and real-world asset (RWA) expertise with Synthetix’s derivatives infrastructure. Derive originally launched as Lyra in 2021, having spun out from the Synthetix ecosystem. Synthetix said the acquisition is part of a broader strategy that includes…

Thailand’s Ministry of Finance reportedly plans to issue $150 million worth of digital investment tokens, allowing retail investors to buy government bonds. The Bangkok Post reported on May 13 that Finance Minister Pichai Chunhavajira announced the initiative at a briefing after the cabinet endorsed the plan.

Understanding Linkage in C When diving into the concepts of storage classes in C programming, one can encounter the term linkage. At first, it may seem daunting, especially when navigating various technical terms like current translation unit, other translation units, same translation unit, and all translation units. In this article, we'll break down these terms to help clarify their meanings and significance in the realm of C programming. What is a Translation Unit? Before we discuss linkage, let’s establish what a translation unit is. A translation unit consists of the source code after the preprocessor has completed its task.

Imagine standing at the threshold of a technological revolution so vast, it could redefine an entire continent's place in global innovation. This is precisely the position Europe finds itself in today. With a massive investment of €200 billion—the centrepiece being five AI Gigafactories—the EU intends not only to catch up but to leap ahead in the global race for artificial intelligence. These Gigafactories aren't ordinary data centres scaled up for bravado. Each one is envisioned to operate at four times the size of current AI factories, powered by around 100,000 cutting-edge AI chips. It's an investment reflecting Europe's determination to assert its technological sovereignty, at a time when the global narrative typically orbits around American dynamism or China's relentless growth.

Ever try to monitor a laser system in real-time... with Excel? Yeah, I’ve been there. A couple years ago, I was asked to build a dashboard for a medspa’s laser lipo machine. They wanted live data. Not just logging—but pulse-by-pulse, second-by-second monitoring. My first thought? “This is gonna be a nightmare.” You’d think there’d be some ready-made solution, especially in places as tech-savvy as a Medspa in Chicago. But nope. At first, we tried to jury-rig a CSV parser that pulled in log files every 10 minutes. Huge mistake. We missed surges in energy output, and one day the machine overheated mid-session. That’s when it hit me: we needed true real-time telemetry. Enter: Node.js (or Python, if that’s your jam). Here’s the quick-and-dirty framework I came up with: Stream the machine’s da…  ( 4 min )

When performing arithmetic with unsigned types in C++, especially with types like std::uint8_t, it's common to encounter questions surrounding modular arithmetic behavior. Specifically, many developers wonder if they can detect when a subtraction operation underflows (i.e., wraps around) without explicitly comparing the two operands. Understanding Subtraction with Unsigned Types In C++, when subtracting one unsigned integer from another, the result is constrained within the limits of the type. For std::uint8_t, this means that values wrap around when the result would go below zero. For example, subtracting 5 from 3 results in 254 due to the wrapping behavior inherent in unsigned types. To validate whether an underflow occurred during subtraction, comparisons are typically used. However, th…  ( 5 min )

Muito já se discutiu sobre as funcionalidades da IA Generativa: modelos de linguagem, engenharia de prompts, automação de conteúdo. Mas o verdadeiro ponto de inflexão não está na tecnologia em si — e sim na sua capacidade de subverter modelos de operação que antes pareciam inquestionáveis. Não se trata mais de "adotar IA" como ferramenta, mas de compreender a IA como um agente de transformação organizacional. Alguns sinais são evidentes: Propostas comerciais que levavam horas para serem montadas agora podem ser redigidas em minutos, com base em dados contextuais e históricos de negociação. Campanhas de marketing não precisam mais ser montadas do zero: são concebidas, testadas e ajustadas por sistemas autônomos com base em comportamento e intenção. A IA Generativa não está apenas automatizando processos. E, talvez mais importante: está alterando o que esperamos das organizações e dos profissionais que nelas atuam. O risco real não é ser substituído pela IA. Não é mais suficiente usar IA. A pergunta, então, não é mais “como aplicar essa tecnologia?”. Sua organização está preparada para repensar seus fundamentos operacionais à luz da Inteligência Artificial Generativa — ou será refém de sua própria inércia? 📌 O debate precisa sair do nível técnico e alcançar o nível estratégico. A IA Generativa não é uma revolução do como. É uma disrupção do por que e para quem as coisas são feitas.  ( 3 min )

In a world where digital transformation is no longer optional, choosing the right cloud provider is one of the most strategic decisions a business can make. But here’s the kicker — most businesses compare providers solely based on cost or brand name. And that’s where they go wrong. AWS has the widest range of services, but are you using them efficiently? Azure integrates deeply with Microsoft products, but is that always an advantage? Google Cloud boasts AI and data capabilities, but what if your use case doesn’t need it? If you’ve ever asked: “Which cloud is the best?” “What’s the real difference between AWS, Azure, and GCP?” “Which provider is right for my workload?” … you’re not alone. We’ve seen startups and even large enterprises spend weeks debating, only to realize they missed core decision criteria. Here’s what often gets overlooked: Compliance & Governance: Which cloud helps you stay audit-ready with less manual overhead? Hidden Cost Models: Are you aware of ingress/egress charges and region-based billing quirks? Developer Experience: How fast can your team get up and running with a new toolset? Multi-Cloud or Vendor Lock-in? Should you optimize for performance, flexibility, or both? These questions aren’t just technical. They’re deeply tied to your business strategy and long-term scalability.

Alright folks, let's talk persistence. If you've been following along with the Vercel AI SDK v5 canary journey, you know we've covered a lot about the new message structures (UIMessage, UIMessagePart), how the client-side state is managed with useChat (especially with that id prop behaving like a mini ChatStore), and how the server-side flow including onFinish and tool calls works. Now, how do we actually save all this rich conversational data so users can come back to their chats? This isn't just about stashing some text in a database anymore. With V5, we're dealing with structured, multi-part messages that are key to those "generative UI" experiences. Getting persistence right means your users get a pixel-perfect restore of their chat, tools and all, and you, the developer, get a system …  ( 37 min )

Alright folks, settle in. We've been exploring the Vercel AI SDK v5 canary in this series, and today we're tackling a big one: Tools. If you're building any kind of agentic behavior, or just need your AI to interact with the outside world (or your own app's functions), this is where the rubber meets the road. v5 brings some serious structure and developer experience improvements to how tools are defined, called, and represented in the UI. As a quick reminder, we're building on concepts from previous posts: UIMessage and UIMessagePart (the new message anatomy), v5's streaming capabilities, V2 Model Interfaces (especially LanguageModelV2FunctionTool), and the overall client/server architecture.

This isn't just a minor update; it's a significant architectural shift that builds on everything we've discussed about UIMessage (Post 1), UI Message Streaming (Post 2), V2 Models (Post 3), and the conceptual ChatStore (Post 4). 🖖🏿 A Note on Process & Curation: While I didn't personally write every word, this piece is a product of my dedicated curation. It's a new concept in content creation, where I've guided powerful AI tools (like Gemini Pro 2.5 for synthesis, git diff main vs canary v5…  ( 29 min )

Welcome back, Linux explorer! Yesterday we met some of the terminal’s superheroes. Today, let’s answer a simple but crucial question you’ll ask a lot in Linux: “Where the heck am I?” In Linux, your file system is your world. And to navigate it like a pro, you need to understand a few basics — like where things are, how to get around, and what those strange slashes and dots mean. The File System Is Like a Giant Tree Where Am I? How Do I Move Around? What’s in This Folder? Real World Practice: Your First Linux Walkabout Quick Gotchas for Beginners Why This Matters Real Talk Think of the Linux file system as one big, upside-down tree: The root is at the top: / Everything else branches out beneath it: /home, /etc, /var, etc. Your files live somewhere on one of those branches.

Deploying a Python Flask app with Docker sounds straightforward… until it isn’t. 😅 Recently, I rolled up my sleeves to containerize and deploy a simple Flask app connected to PostgreSQL. While it seemed like a walk in the cloud, I ran into several walls—but breaking through them made the win even sweeter. Here’s how it all went down 👇 I started with a basic Flask app that connects to a PostgreSQL database. My directory looked like this: 📁 python-docker-project/ ├── Dockerfile ├── compose.yml ├── app.py ├── requirements.txt └── README.md My app.py had two routes: /: returns a simple greeting /db: connects to PostgreSQL and returns the DB version The goal? Run this app in a Docker container and use Docker Compose to spin up both the app and a PostgreSQL service in one command. I created …  ( 4 min )

Been neck-deep in the Vercel AI SDK v5 canary builds for a bit now, and it’s high time we talked about one of the real workhorses under the hood: the streaming mechanism that powers those slick, real-time chat UIs. If you’ve been following this (hypothetical!) series, you’ll know we've touched on the new UIMessage structure (Post 1), the general UI Message Streaming Protocol (Post 2), those shiny V2 Model Interfaces (Post 3), and the client-server decoupling (Post 4). Now, let's get into the nuts and bolts of how these streams actually zip across the wire and light up your UI. This is Post 5, and we're focusing on how Server-Sent Events (SSE) are the engine driving these UI Message Streams, making for a super responsive user experience.

Today I built a secure shared file space using Access Control Lists (ACLs) on Red Hat Linux. This project is very practical and directly aligns with RHCSA exam tasks around user permissions, groups, and access control. 🔧 Objective Create a shared folder for multiple users Apply ACLs to define fine-grained permissions Test and verify ACL behavior with different users 📚 RHCSA Skills Covered ✔ User and group creation ✔ Setting standard and extended permissions ✔ Using setfacl and getfacl for ACL management ✔ Troubleshooting permissions 1️⃣ Create Users and Groups sudo useradd alice 2️⃣ Create a Shared Directory sudo mkdir /shared This allows only the owner and group members to access by default. 3️⃣ Apply ACLs for Fine-Grained Control Grant full access to alice, read-only access to bob, and deny access to charlie. sudo setfacl -m u:alice:rwx /shared 4️⃣ Verify ACLs getfacl /shared Example output: user::rwx 5️⃣ Test Permissions Switch to each user to test access: su - bob su - charlie 🧪 Try It Yourself Create a “Finance” group with specific ACL access to /finance Remove ACLs with setfacl -x Make default ACLs apply to all new files in /shared: ✅ Recap Task Tool/Command Create users useradd, passwd Create shared folder mkdir /shared, chmod 770 Apply ACLs setfacl -m u:user:perm /path View ACLs getfacl /shared Remove ACLs setfacl -x u:user /shared 🎯 Why This Matters (RHCSA) ACLs provide fine-grained access control that regular Linux permissions cannot. RHCSA tests your ability to: Set, modify, and remove ACLs Combine ACLs with standard permissions Troubleshoot permission issues This is an ideal exam and real-world scenario for securing shared data.  ( 4 min )

When working with SQL, one of the common inquiries developers face is whether the CASE statement in their SELECT clause effectively filters records or if they also need to replicate the same conditions in the WHERE clause. This question is particularly pertinent when grouping certain entries, such as teams, and seeking clarity on how SQL evaluates these expressions. Understanding SQL CASE and WHERE Clauses The CASE statement is primarily used to create conditional logic inside your SQL queries, particularly in the SELECT clause.

Introduction Docker registries are essential nowadays in a world of containerized workloads. Want to run your app on Kubernetes? You need to push it to a registry first. If you don't want to pay for a managed, private registry service, you self-host your own. The biggest pain point of Docker registries is storage. If you choose to store registry data on a local disk, you are limited by capacity. Over time, registries accumulate a lot of garbage in the form of blobs referenced by old images that are not needed anymore. Many registry implementations, such as CNCF Distribution, offer garbage-collection mechanisms to delete unreferenced blobs and free up storage space. However, for that to happen, old images (tags) referencing them have to be deleted first. There are implementations like Har…  ( 4 min )

Read this article on Signadot. Testing in-progress changes together, across services, without merging early or coordinating a full rollout, shouldn’t be so painful. “Hey, don’t merge that yet, I still need to test with my service.” Sound familiar? Coordinating changes across microservices during feature development always starts simple. When your whole stack fits in a single repo or an EC2 box, it’s not a big deal. But fast-forward a bit, and you’re juggling 20, 40, maybe hundreds of services owned by different teams, moving on different timelines, and depending on each other in subtle, undocumented ways. Suddenly, a small change to an internal API breaks someone else’s staging. A frontend pull request (PR) is stuck waiting on a backend deploy. You’re in Slack going, “Can someone redeploy …  ( 6 min )

As a developer, my core expertise lies in frontend and mobile app development using React Native. Given that both frontend and React Native leverage JavaScript, I've explored cross-platform solutions like react-native-web. However, this approach often means sacrificing certain advantages inherent to each platform, such as straightforward CSS styling or enhanced SEO capabilities. In my frontend work, I also utilize a range of technologies tailored to specific client needs, including Astro.js, React, Next.js, or even vanilla HTML, CSS, and JavaScript. This often leads me to the fundamental question: how can we write code once and deploy it across web, Android, and iOS while maintaining excellent design, SEO, and performance? My current answer points towards the power of Artificial Intelligen…  ( 3 min )

When I started learning FE, I began with React - like many others. It's the most popular library, and if you search for job opportunities there are abundant. And at that stage, you should have only one goal/priority, getting hired and gaining experience. So it's only reasonable to start with React. I learned React through class component, and yes, they are deprecated. But understanding gave me deeper grasp of how React works under the hood (lifecycle methods, binding, rendering). Eventually, I landed my first job working on Vue project. It wasn't a conscious shift, but it was a opportunity. Over time I came to appreciate Vue, and while writing this, I feel like a need to promote it. Especially through lens of someone who also mentored new developers in React, on bootcamp.

E talvez você se identifique... Desde 2023 venho trabalhando como dev profissionalmente. Sempre fui o tipo de dev "raiz", que gostava de codar, passar horas (ou noites inteiras) imerso em projetos que nem eram meus. Saí de outro estado pra Natal-RN com a cara e a coragem. Aluguei um canto só com a roupa do corpo e fui construindo meu espaço — e finalmente, trabalhando como dev. Amava o que fazia. Mas com o tempo, o cenário mudou. A inflação subindo, custo de vida aumentando, e meu salário... estagnado. A vontade de procurar empregos melhores chegou, deu certo, o salário subiu... etc. Mas há alguns meses, no fim de 2024, percebi que tinha perdido o amor pela programação. O código virou só uma moeda de troca. Eu só queria o dinheiro. E aí veio o maior problema: ❌ Não me atualizei ❌ Fiquei pra trás ❌ Acabei o último contrato PJ e tive uma dificuldade ENORME pra me realocar Enquanto devs realmente bons escolhem onde querem trabalhar, eu tava no limbo, tendo que dar vários passos pra trás. A pergunta martelava: “O que tem de errado comigo?” Depois de muito pensar (e muita autoanálise), percebi: Eu tinha perdido meu lado dev raiz. Aquele que curte aprender, codar por prazer, mergulhar nos porquês das coisas. Tava tudo no automático. Então, comecei do zero de novo. Voltei pro básico: codando, lendo, contribuindo, errando, aprendendo. Dessa vez com prazer. E percebi que tinha me desviado do meu caminho. Antes de olhar pra vaga, eu perguntava: “Quanto paga?” Se não fosse "bom o bastante", eu nem tentava. Agora, a primeira pergunta é outra: “O que posso aprender aqui?” Voltei a contribuir, voltei a movimentar meu GitHub, voltei a fazer parte da bolha dev disso que eu gosto, que eu sempre sonhei, e de onde eu simplesmente me perdi. E aí? Você ainda é dev, DEV? Ou tá só no piloto automático?  ( 3 min )

Why I Built Sona Modern programming languages weren’t built with neurodivergent or first-time coders in mind. That’s a gap I couldn’t ignore. As a self-taught developer, I spent years battling syntax errors, inconsistent tooling, and steep learning curves — not because I lacked motivation, but because the language design just wasn't made for brains like mine. So I built Sona — an open-source programming language designed to simplify coding, reduce friction, and empower creativity. What Makes Sona Unique? Minimal, readable syntax (inspired by Python, Rust, and Go) REPL-first development (Sona v0.4.3 just launched!) Modules that feel native and expressive (import fs, stdin.input(), etc.) Designed for focus + accessibility, including neurodivergent users Fully open-source, interpreter built with Python + Lark Current Progress ✅ Interpreter up to v0.4.3 ✅ 12+ core modules complete (fs, http, json, env, stdin, etc.) ✅ REPL mode: multiline function support, :env commands, graceful errors ✅ Preparing for public alpha (v1.0) Call to Action This is your invitation to help shape the future of dev tooling. 👉 Try Sona.

When set to imagine practical, easy-to-use, lightweight applications of Divooka, a visual novel game framework is one of those that came to mind. Visual novels should be such a straightforward type of application to build, yet surprisingly, it's not generally easy to find ready-to-use tools available for them. Of course, one can use Defold, Godot, Unity 3D, or even Unreal to build such a game — or the more technically inclined might just use SFML or other lower-level graphics libraries. Still, it's a lot of work to get a conceptually straightforward task done. Much like building an LLM agent or chaining different AI services together — it's straightforward, it's visual, it describes some kind of workflow or dataflow — then it's a good fit for Divooka. Visual novels fundamentally consist of…  ( 4 min )

If you're transitioning from JavaScript to TypeScript, you may encounter type-related issues that can be frustrating. In this article, we'll delve into how to properly push an object into a MongoDB array using TypeScript and address common errors you may face in the process. Understanding the Error Your current error occurs because TypeScript is more strict with types compared to JavaScript. The error message you’re experiencing: Type '{ answers: {}; }' is not assignable to type 'PushOperator'. This suggests that TypeScript expects a specific type for the answers field, but you are passing an empty object {}, which doesn't match the expected type. Setting Up Type Definitions To resolve this, you need to define the type of the answers array properly. Assuming that answerObj represents the …  ( 4 min )

A Compiled Programming Language is one where the source code is translated into manchineel code (executable code) by a compiler before the program can run. [Source Code] → (Compiler) → [Machine Code] → [Executable File] [Executable File] → (CPU executes) → Program runs _Source Code _ :- A programmer writes a code, which is called human readable language. Compiler :- A special program, the compiler, takes the source code as input. Analogy Machine Code :- Compiler translates the source code into manchineel code, which is a set of instruction the CPU can understand. Executable file A structured file format (like .exe, .out, .elf etc) that contains: Machine Code Metadata (like symbol tables, headers, memory layout) This is the final output produced by the compiler.

We are living in an exciting era for software development. It has always been an industry of constant evolution, but the rise of artificial intelligence has multiplied the productivity of those who adopted it early. This new reality, with teams capable of building faster than ever, shines a light on something many leaders still don't want to see: the main bottlenecks are often not in development, but in how we manage processes and make decisions. When developers become more efficient, tasks are delivered faster, and AI tools can automate or accelerate repetitive work, the real obstacles are exposed: unnecessary processes, unproductive meetings, outdated hierarchies, and a constant need to “feel in control.” All of this slows teams down. At the root of the problem is often a human flaw: dis…  ( 5 min )

Solana has made a name for itself in the blockchain space as one of the fastest and most scalable platforms in the industry. But what’s the secret behind its speed? It all starts with time. More specifically — Proof of History (PoH). In this blog post, we’ll break down what PoH is, how it works, and how it helps Solana achieve high throughput, low latency, and fast finality — all in a way both beginners and developers can understand. In most blockchains (like Bitcoin or Ethereum), time is a vague concept. Each block is timestamped by validators or miners — but there’s no standardized clock. This creates a challenge when trying to organize transactions quickly and securely. Nodes must constantly communicate to agree on order, which slows everything down. 🧠 Enter Proof of History: Time Befo…  ( 4 min )

They promised speed, simplicity, and a better DX. What we got was a set of beautiful lies, niche fantasies, and philosophical dead ends. Modern frontend frameworks love to sell a dream.

Astro sells the fantasy of zero-JS by default. Clean HTML. Minimal payloads. Islands of interactivity. Astro is just Gatsby rebranded. It inherits the same flaw: It works great until your app grows. Then you’re back to hydrating islands, shipping frameworks, and juggling scripts. Astro’s true n…  ( 6 min )

My AI-Driven Coding Workflow: Fast, Dirty, Smart For years, I’ve followed a simple, effective development rhythm: Refactor the existing code to make space for what’s coming. Spam code the new part—quick and dirty—just get it working. Refactor again, clean it up, make it readable and reusable. Commit. It’s always worked. It still does. But now there’s AI. The last few years have made AI coding assistants usable, stable, and practical. So I’ve adapted my process. Here's how it looks today: Start with a clean working tree. No changes, no mess. This has always been good practice, but it’s critical now. Why? Because AI can (and will) generate garbage. If it does, you need to scrap everything fast. You can’t "undo" AI-generated logic. You just reset. Whether by hand or with AI help, p…  ( 4 min )

A good programming language should model it's domain in the most straight-forward way - that way there are no rough edges, no friction. The programmer has no gotchas to work around, the code flows naturally. Distributed programming in modern mainstream languages is not that experience, and in this blog we will go over a part of the solution, the one having to do with coordination of distributed actors. OOP models a program as an interaction between objects, and its implementation in most modern languages work well in a single-threaded context. But as soon as concurrency gets introduced - you either introduce a whole different mechanism than the objects you've been building with up til this point (threads and mutexes and thread-local variables), or an event loop, and a split in the laguage …  ( 7 min )

When you need to deploy a simple HTML page (like one generated by AI), or quickly share some design drafts, or deploy a small website from a ZIP package, what tools do you usually use? A lot of the time, you either find hosting too expensive or the setup process too complicated. Recently, I discovered an online tool called Pages Drop, and it seems pretty neat. It's essentially a place for hosting and sharing files, and crucially, it's completely free and very convenient to use. Why do I think it's worth sharing? Mainly for these reasons: Although there are similar products, such as Tiinyhost, Static App, etc., the free plans have very few resources and are very restrictive. The free tier is quite generous: Completely Free: The core features are genuinely free to use. Unlimited File Upl…  ( 4 min )

Hello Dev.to readers! This time, we decided to adopt a slightly more serious tone and tackle a serious topic. In our New Gen Atari project, we hit rate limits hard. After that mess, we finally turned to the documentation. To keep you from falling into the same trap, I wanted to write a piece with above-average seriousness. API rate limits cap the number of requests you can make to an API in a given timeframe (e.g., 100 requests per minute). Exceeding these limits results in rejected requests, disrupting your application. They’re standard across platforms, whether free or paid tiers. Limits serve three key purposes: Security: Protect servers from malicious request floods. Resource Management: Ensure fair access for all users. Cost Control: Prevent excessive server resource consumption. Igno…  ( 5 min )

I recently set up Home Assistant and started exploring the world of smart home automation. One of my first—and now favorite—automations is part of my morning routine. Let’s be honest: waking up early sucks. Alarm clocks are loud, annoying, and stressful. I wanted something more peaceful to get me out of bed. And I found it… I wake up through the smell of coffee and the gentle bubbling sound of a moka pot. 😌 I bought this moka machine from Bialetti: https://www.bialetti.com/ee_en/moka-elettrika.html It’s called the Moka Elettrika, and it runs on electricity. I connected it to a smart plug that’s controlled by Home Assistant. At 7:55 AM, the smart plug turns on, powering the moka pot. The moka starts brewing right away. At 8:10 AM, the plug turns off again. By the time I'm awake, the apartment smells like fresh coffee, and I hear that cozy, comforting moka pot bubbling away. It’s such a calm and natural way to wake up—no loud noises, no stress. This tiny automation has made a huge difference in how I start my day. If you're into smart home stuff (or just love coffee), give it a try!  ( 3 min )

This post was originally published on Medium. I'm resharing it here for fellow developers and tech learners focused on productivity and AI tools. In 2025, AI is no longer just a buzzword. It’s a reliable assistant, a writing partner, a research analyst, and even a decision-making guide. If you're a solo developer or working in a small team, AI tools can easily fill the role of a full-time assistant — helping with writing, planning, organizing, and automating your workflow. Here are 5 AI tools that can genuinely replace or outperform a human assistant: ChatGPT (OpenAI) Research, summarization, planning, brainstorming GPT-4 Turbo supports long context conversations Great for developers to generate test cases, ideas, and plan features Notion AI Meeting note summarization, task extraction, and content generation Blends into your project workflows perfectly Dev teams can use it to log retrospectives, docs, and updates GrammarlyGO Tone refinement, rewrites, and quick replies Useful when writing client emails, proposals, or documentation Magical Automates repetitive typing and form-filling You can set text snippets for common code comments, support replies, etc. Claude AI (Anthropic) Reliable for long-form Q&A, documentation, and secure data handling Great for knowledge-heavy tasks and documentation generation If you're spending time on repetitive tasks — planning, writing, summarizing — these tools can handle them for you.

Today we'll master two powerful loop types: 🔢 For loops - when you know exactly how many times you want to repeat something ⏱️ While loops - when you want to keep going until a condition changes A for loop works like this: Specify what you want to iterate through For each item, execute the indented code block Move to the next item and repeat until you've gone through everything name = "Ridwan" for i in name: print(i, 'i') …  ( 7 min )

There’s a strange paradox in tech: someone can be a solid developer, lead projects, write clean code, and still fail interview after interview. Not once, but over and over again. And we’re not talking about juniors. I’ve seen senior engineers freeze mid-sentence, forget terminology, or just walk away feeling like they bombed, even though they knew the answers. If that sounds familiar, you’re not alone. I’ve worked with developers for years: hiring them, preparing them, evaluating them. And here’s the truth: if you’re struggling with interviews, it doesn’t mean you're unqualified. It means the format is broken. In theory, a technical interview checks if you know your stuff. In reality, it’s a pressure cooker. Here’s what it throws at you: limited time unfamiliar phrasing of questions z…  ( 4 min )

Introduction In Rust, handling files and processing their content efficiently is crucial, especially when dealing with potentially large files. A common scenario involves reading lines from a file and splitting those lines into individual tokens based on whitespace. However, you might encounter a compilation error due to how Rust handles lifetimes and references. In this article, we will explore the origin of this issue and provide a solution that returns an iterator of owned String values without allocating too much memory upfront. Understanding the Compilation Error When you attempt to return a value that references function parameters, Rust will flag this as an error. Your original code attempts to utilize the .split_whitespace() method, which returns slices of the original string. The …  ( 4 min )

Google just paid $1.375 billion to Texas for secretly tracking users, collecting geolocation, voiceprints, and facial recognition data even with privacy settings disabled. The headlines scream “Big Tech scandal” — but here’s the real message: If your app handles user data, you’re part of this conversation. And if you’re using tools like Firebase, Google Analytics, or Meta Pixel in production without understanding what’s being captured, you’re one misconfigured SDK away from a privacy disaster. 🔍 So, What Should Developers Do? Re-check what your analytics are logging. Google Analytics 4 tracks more than you think by default, especially if you’ve enabled Enhanced Measurement. Alternative: Try Plausible or PostHog. They’re privacy-first, self-hostable, and GDPR-compliant. Audit your use of location data. If you’re using React Native Geolocation, are you requesting location only when needed? In web apps, check the navigator. Geolocation calls, are you storing or sharing that info? Facial recognition libraries? Tread carefully. Read your dependencies’ privacy policies. Cookies and localStorage: keep them clean. Use libraries like cookie-consent and tools like Cookiemonster.dev to flag risky behavior early. 🧠 The Bottom Line As devs, we build the foundation of user experiences, and that includes privacy-first defaults. Not because it’s trendy, but because it’s now a requirement.  ( 3 min )

When we talk about giving feedback, most of the advice out there focuses on how to say the thing. But what I have learned over time is that the real magic happens before the conversation even starts. Setting the stage can be the difference between feedback landing as a gift or feeling like an attack. Some of the most effective feedback conversations I have had - both from giving and receiving - actually started with a letter. When there's a lot to say, taking the time to write it down helps in more ways than one. It lets you rewrite, refine, and make sure the message you intend is the message that gets carried forward. You can catch moments where your tone might be too harsh, or where you're speaking from frustration instead of clarity. From the recipient's perspective, it's a game-change…  ( 4 min )

Welcome to the next pikoTutorial ! Imagine you're building an application that processes some data and once it's done, the user needs to be notified about the result. Since you don’t want to hard-code the notification logic, it’s better to allow the user to register a custom function that will be called automatically after the data processing completes. std::function for callback registration One of the most flexible ways to implement callbacks in C++ is by using std::function. std::function can store and invoke any callable object (functions, lambdas, or function objects) that matches a specific signature. The overall syntax is: std::function name; Let’s define a ProcessData unction that accepts a callback and notifies the user once processing is complete. #include #include // Type alias for the callback type using CallbackType = std::function; // Function accepting callback as an argument void ProcessData(const CallbackType& callback) { // Simulate data processing std::cout << "Processing data" << std::endl; // Notify user via callback callback(true); } // Callback function definition void Callback(const bool result) { std::cout << "Callback called! Result: " << result << std::endl; } int main() { // Register a callback using an existing function ProcessData(Callback); // Register a callback using lambda function ProcessData([](const bool result) { std::cout << "Lambda called! Result: " << result << std::endl; }); // Register using callable object CallbackType cb = [](const bool result){ std::cout << "Callable called! Result: " << result << std::endl; }; ProcessData(cb); }  ( 3 min )

In the world of keyboards, the WASD keycaps hold a special place. These four simple letters—W, A, S, and D—are often seen as the backbone of gaming. For most gamers, they’re more than just letters on a keyboard; they’re the foundation for movement in the virtual worlds they explore. But like all great inventions, the history of WASD keycaps goes beyond their initial function, evolving to become a symbol of gaming culture and a feature beloved by enthusiasts. Let’s take a journey through time to uncover the origins, evolution, and significance of WASD keycaps. The WASD layout, used predominantly in first-person shooters (FPS) and other action games, has become almost synonymous with gaming itself. But where did it come from? Originally, keyboards were designed with the arrow keys or the num…  ( 6 min )

🔍 Introduction JavaScript is packed with powerful features—but many developers stick to the basics and miss out on time-saving gems. In this post, I’ll show you 7 underrated tricks that can simplify your code, enhance readability, and make you look like a JavaScript pro in 2025. ?. const username = user?.profile?.name || 'Anonymous'; ✅ Avoids errors when deeply nested properties are undefined. Cleaner and safer than long logical chains. ?? const count = inputValue ?? 0; ✅ Returns default only if the left-hand value is null or undefined (unlike ||, which includes 0 or ''). const { title: blogTitle } = post; ✅ Grab and rename properties in one line. const isAvailable = !!value; ✅ Quickly turn any truthy/falsy value into a clean true or false. const user = { name, age }; // same as { name: name, age: age } ✅ Reduces repetition when property and variable names match. const key = 'theme'; const settings = { [key]: 'dark' }; ✅ Build flexible objects based on runtime values. const status = `You are ${loggedIn ? 'logged in' : 'logged out'}.`; ✅ Great for short conditional strings and UI feedback. These tricks may be small, but they add up to cleaner, more elegant JavaScript code. Whether you're working on a side project, fixing bugs, or building production apps—mastering these patterns will level up your skills. ✅ Try using at least 2 of these in your next app! 💬 Got a trick of your own?

Short answer: yes Over the past 5 years, I've learned a lot about communities. I've made many mistakes: I could probably create a 'Community Mistakes 101' crash course! Unfortunately, they didn't teach that in high school, which would have been useful. I learned that a community absolutely must have a specific goal. I also learned that while having an open community is good at the beginning, it becomes nearly impossible to handle and moderate long-term unless you dedicate an insane amount of time to it (trust me, I tried) or you are a bored millionaire lying on the couch all day (which is not my case). Regarding promotion, I've made the mistake in the past of overpromoting communities I created, simply because I was overjoyed about the new adventure. I now think this approach is wrong. it's better if people discover the community on their own. But now I really feel I am ready to do it right. So, why am I writing this? The reason is simple: I've just a new community, and I've decided to use Twitter (sorry, X) for it. The goal is to introduce curious developers to the Rust programming language and help them understand as much as possible. Joining this community is free, just request to join. The link is in my profile, but if you're lazy and want to be invited, just reply below. For now, I am not accepting moderators, but moderators might be chosen from among the active members in the future. Let's Crush it !!!🔥  ( 3 min )

When trying to SSH into a newly created Linux server, you might run into a common error like this: $ ssh user@your-server-ip The authenticity of host 'your-server-ip' can't be established. ED25519 key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Any other names do not know this key. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'your-server-ip' (ED25519) to the list of known hosts. user@your-server-ip: Permission denied (publickey). This error simply means: “SSH couldn’t find a valid key to authenticate you.” ✅ What Actually Worked ssh ubuntu@your-server-ip You used the correct approach by providing the private key file: ssh -i /path/to/your-key.pem ubuntu@your-server-ip And this worked — because the server was expecting authentication via a specific private key (.pem file), not a default key from ~/.ssh/id_rsa. 🔍 Why This Happens key-based authentication only for better security. When you create a VM or instance, you’re often required to either: Upload your public key, or Download a .pem file that matches the server's authorized key If you try to SSH without specifying the .pem file, the SSH client defaults to using standard key files like ~/.ssh/id_rsa, which likely don’t match what the server expects. 🛠️ How to Avoid This in the Future Always specify the key manually with -i OR Add the key to your SSH agent so it's picked up automatically: ssh-add /path/to/your-key.pem 🧠 Pro Tip chmod 600 your-key.pem This keeps your key file secure and prevents SSH from refusing to use it.  ( 3 min )

When working with C++ and interfacing with API functions, developers often encounter the challenge of passing large blocks of data. In your case, you're constructing a large string using std::ostringstream and need to send this data to an API function, API_function, defined as int API_function(const char* data, int len). The issue arises when the data contains null bytes (0x00), resulting in data truncation. Let’s address how to pass this std::ostringstream payload effectively to the API function without copying it, especially in the context of constrained environments like microcontrollers. Understanding the Issue with Null Bytes The problem you're facing is due to the way C-strings (null-terminated strings) work in C++. When you use payload.str().c_str(), you get a pointer to the interna…  ( 5 min )

Hi everyone, The game is called BrainsIAAndPixels: it's going to be a 3D title with a pixel art style (even though it's set in a 3D environment), where NPCs won't be rigidly "scripted" but will instead be controlled by real artificial intelligence using pre-trained models running locally. The goal is to create a game where NPCs understand and react to what happens around them, rather than just following a fixed pattern. I'm using Python in Godot, and the AI part relies on ONNX models. Right now, I'm setting up the development environment, testing the AI integration, and building the foundations. The plot and genre aren't fully defined yet (I'm torn between survival, something narrative-driven, or similar), so any ideas are more than welcome. Thanks!  ( 3 min )

Today's note is about something that I, as a new Mac user, had to deal with while setting up my work environment. TL;DR: To run NVDA and JAWS on a Mac, you need to install Windows 11 for ARM in a virtual machine like UTM, and map a spare key to the Insert key with SharpKeys. According to the WebAIM Screen Reader User Survey #10, Windows-only screen readers NVDA and JAWS are used by the majority of users. Just like browsers, screen readers have differences in how they present information, so it's always a good idea to test your website or app using different browser/screen reader combinations.

When working with object-oriented programming in Java, it's common to encounter situations where you want to pass a collection of objects from a subclass (child) to a method that expects a collection of objects from a superclass (parent). This might seem straightforward, but the compilation error you're facing highlights a key aspect of Java's type system, particularly with generics. Understanding Java Generics Generics in Java provide a way to specify a type parameter when defining classes and methods. When you declare a method that takes a list of a specific type, such as List, it expects a list that strictly contains Parent objects, not Child objects. Even though Child is a subclass of Parent, List is not considered a subtype of List. This is due to Java's type sa…  ( 5 min )

In Laravel projects or any large scale PHP application it's common to create helper files that contain reusable functions. These helpers make your code cleaner and more efficient. But there's a common issue, defining the same function more than once will cause a Fatal error.. What's the problem? If the same function is declared twice, PHP will throw an error like this: Fatal error: Cannot redeclare function_name() This often happens because of: Repeated includes: Package conflicts: The safe solution To prevent this issue, wrap your helper functions like this: if (!function_exists('sayHello')) { function sayHello() { return 'Hello!'; } } This way, if the function already exists, PHP will skip redefining it, and your app will keep running smoothly. In Laravel projects Even with Laravel’s powerful autoloading and service container, this pattern is essential. It keeps your project safe from unexpected conflicts and ensures maximum compatibility especially when working with custom helpers or external packages.

Hello everyone. A couple of days ago, I talked about the basic layout and custom navigation bar when developing HarmonyOS applications through Uniapp. Both of these were limited to the development on the page. Today, we attempt to perform some data operations to share the contents of the optional API and the composite API. The script code part of the homepage project code we initialized is usually like this: export default { data() { return { title: 'Hello', } }, onLoad() { }, methods: { } } It can be seen that it is divided into three parts. As the name suggests, the data part is used to store data, onLoad is the event executed when the page is loaded, and methods is used to store event methods.

For years, Retrieval-Augmented Generation (RAG) has been at the core of many advanced AI systems. It provided a smart way for models to retrieve relevant documents and generate answers based on that data — allowing AI to access fresh, real-world information without retraining. But now, with the launch of Gemini 2.0 Flash, a question looms large in the AI community: Let’s break it down. 🔍 What is RAG and Why Was It a Big Deal? Think of it as an AI with a smart search engine in its brain. It was especially useful in: Enterprise search tools 🚀 What is Gemini 2.0 Flash? But don’t let the word “Flash” fool you. It’s not just about speed. It combines: Long-context understanding 💥 So, Is RAG Really Dead? Gemini Flash isn’t just competing with RAG. Instead of setting up a full retrieval pipeline — with vector stores, chunking, embeddings, re-ranking, etc. — Gemini Flash can ingest large documents directly, remember what matters, and answer complex questions in real-time. That means: Less engineering overhead 🧠 Why This Matters for Developers and Businesses For businesses, this translates to: Faster time to market 🔮 The Future: RAG 2.0 or No RAG at All? Models like Gemini 2.0 Flash are making RAG optional, not essential. We’re entering a new era where LLMs are becoming self-reliant, real-time, and capable of processing massive amounts of information without help from external retrieval tools. 🧩 Final Thoughts Gemini 2.0 Flash isn’t just fast. It’s redefining the architecture of how we build with AI. So the question isn’t just “Is RAG dead?”  ( 4 min )

Mastering APIs with a Simple Restaurant Analogy By Dhanian | Author of How APIs Work: The Invisible Force Behind Modern Apps APIs power nearly every app you use today—from weather updates to payment systems. But what is an API, and how does it work? Let’s break it down using a familiar setting: a restaurant. This analogy will help you visualize the invisible magic behind software communication. An API (Application Programming Interface) is a bridge that allows two systems to communicate. Think of it as a messenger that delivers your request to a system and returns the response back to you. In software terms: The client (like your app or browser) wants something. The API receives the request and talks to the server. The server sends back data via the API. restaurant to understand how APIs …  ( 4 min )

At first, I didn’t really understand what the purpose of the layers in Tailwind’s CSS system was.

Recently, on LinkedIn, I've been seeing the posting from Duolingo's team about how they have decided to do away with the whole UX wireframing process. While that might sound rather controversial to most folks, as an experienced professional, I actually do kinda understand where they might be coming from. You must understand that I've been drawing UX wireframes since early 2006. That's almost two decades now. I've done so many wireframes that by now, a lot of what I can do on paper using sketches or even the digital form, I can mentally visualize them inside my head, and I can convert most of them smoothly into UI prototypes. But that is only because of a few factors: I've been doing this a long time. I've become very good at anticipating what a potential user would want. I can easily visua…  ( 6 min )
